Just read your bit about the brakes, agreed. It's gonna be an expensive month April as the front discs are bent too, i've never changed them but they progressively getting worse under heavy braking...Especially after yesterday's heating... And I'm not going to buy cheap stuff either. The lower arms used to be a problem but were changed to poly so I'm pretty sure it's not those. Pump and fluid are going too, that steering locking up thing although it's happened twice in 6 years I don't know how it can happen and have been concerned ever since that it could happen at speed, and this car is like a dead steering a tank when the assistance has gone.

Once you get the CO set up spot on it'll be at its best. A base setting will be 'close' but you want to see it set based on what's coming out the back, because as you know, that tells you exactly what's going on at the front in the big, cast, timed-explodey box. When these older EFI BMW's are set to the factory CO readings and are running right they shouldn't even far off passing the MOT CAT test. My MOT chap was a bit amazed at the read outs. I'm amazed at what the L-jet system manages against other FI systems of the day. Compared to K-Jet it's not exactly far off being a modern management system.

Cold start this morning, about 8.5 degrees and it starts and runs but it's like the auto choke of some sort is missing so it sits at 550 ish rpm but it doesn't stall selecting a gear. It ran for a little bit and I turned it off and then back on and the idle came in at 750ish until some heat got through it, not operating temp, and the revs at idle dropped to the usual 650rpm... But no stalling or revs dropping out so that's a result. Still got that low misfire type rumble at 2000rpm though. The cold start is disconnected so I'm expecting some disruption initially starting it but that rumble suggests something mechanical is not pulling its weight. At least i have a base to work from now as discussed above and now I can check and replace tired components. Next is to make a list of stuff to replace!

Fixed, confirmed and legit. It was almost a pleasure to start and drive this morning (tracks bad on worn roads). What I want to know is how the hell has it run with that screw tight for 6 years? I can only think that it was one of the other problems causing it to rev high at idle so that screw was mucked about with to get the revs down? Onwards and upwards!

There's an inlet manifold for sale on the bay which comes with injectors, regulator and throttle body although it looks like is off of a manual as the throttle position sensor is different (motronic 1.0). I want a spare set of injectors to get balanced and I could use another fuel regulator to try out to see if mine is a bit dud. Is it worth forking out the 150 notes for it? Help me decide. I can't use the position sensor as my auto is a completely different set up but I don't know if I can use the body either? You'd think that they would be the same unit... anyone know?

Got it did. Fingers crossed I didn't just buy an extremely heavy ornament. Also got suitable oil for the age/ mileage, power fluid, correctly listed Bosch plugs, some testing toolage, injector seals and something else of which I cant place right now. April's budget blown. I've been using it daily, about 100 miles a day and it hasn't got any worse, most of the time it's pretty good. I'm not really a believer of premium fuels but where I go now there is a tescos which I'm forced to use as there is no other garage that i know of around the area yet, i'll only use momentum in these places and it would seem the BM is liking the taste of it as I've noticed better/ smoother runs on it... Suits me, I've got a club card.

Turned up today at warp speed! Unusually for me it appears a lot better than the photos showed. 3 of the injectors look different in appearance in the manifold but the same outside it. Be nice to test those later at some point. The regulator is a spare which I will probably chuck on if the system pressure is incorrect. The throttle body IS the same as mine so that's cool, needs some serious cleaning though as there's a bit of storage dust in there! Fuel rail is a fuel rail, mine has black paint chipped off it so I can give this one a makeover to swap over one day. The actual manifold has a nice finish to it although a few bruises from storage, it's fairly good looking and better than the one I have... and lastly, a nice little surprise underneath of what looks like a fairly new cold start valve! Got some spares and stuff to work on now which may have saved me a small fortune... if it all works of course! So far, the car is performing well, it has got better and I think the long motorway runs I'm putting it through has helped although it has a grumble at me on cold starts but even just after a short while is quite happy and hasn't stalled at all or given the signs that it wants too and the revs are stable...he says, hand resting on a fine piece of English oak... Got a fuel pressure tester coming which was a bit dearer as the cheapo ones don't cover the Bosch system and the proper listed plugs are on their way. An oil change and blow the air filter out and then I'll get the emissions read. The two issues to iron out now is the slight rich smell coming from the exhaust and the cold start which is nearly there but as we're not seeing below 6 degrees now in the morning, this issue is going to get hard to resolve... until next winter!

Good call on the AFM and although this one checks out to be serviceable and has been repaired and set up by Moi, who generally knows what he's doing (most of the time...), a spare to compare and refurb is on the cards. The back fire blew the cursing wibblepoo out of it. I'd like to replace the air temp sensor in it... can I find one... NOT WHERE I'M LOOKING I CAN'T!

Mine ran rich when I first had it, they always seem to, so you're not alone! I would suspect the pressure regulator is shafted, get a bit of clean pipe and connect it to the reg, then blow down it, you shouldn't be able to.. if you can, the diaphragm is toast.. it's an easy change and very common.. next, vacuum lines are always an issue, on your M30 there's loads, and you don't need half of them.. if you put your hand under the inlet manifold you'll feel three under the 'block', one goes to the pressure reg, the other two are surplus and go to the interior temp sensor and the crankcase vent, put new pipe on all and block them with a screw.. then go check the pipes on top of the engine, the crank vent has a tiny nipple vacuum pipe that, over time will leak like a sieve, adding more unmetered air into the mix.. so seal that up good.. then whip the egr valve off and give it a clean with some carb cleaner (also a really common issue) Then, the bodged AFM really needs to go, if someone has been fiddling I would suggest they may have been bothered to whip the lid off and change the spring setting inside, either way it doesn't sound great so I'd find a breaker and get another that's factory standard.. the trouble is people get a weepy injector or a vacuum leak and start twiddling the AFM!
Lastly, I fought with my 'smelly rich' running for over a month before realising it was actually running lean! So a gas analyser is definitely the way forwards.. or just a meter and a cheap generic lambda sensor and bodge your own..
Oh and raw fuel smell, go to the fuel filler and pull out the rubber surround, there's three vent lines that run to a charcoal box in the boot.. these are always porked.. change them out and enjoy a tank full without feeling like you're huffing gas every time you open a window!

Thanks, I've covered mostly everything and it's running not far from tip top now especially after yesterday's full blown extensive service. I'm waiting on an injector service kit, tester and fuel pressure tester to sort those, I've a few spares now to play with as well as a regulator and cold start valve. Valvoline max life went in yesterday, along with the specified Bosch plugs rather than the NGK it's been running on and the ones that came out were clean which I'm pleased with. The brake issue in traffic may be gone now too as I'm changing out the power fluid weekly via the resevoir to save disturbing the plumbing. The first change made a hell of a difference with no noise from the pump anymore (it had a moan at me initially) and a consistent pedal. Steering feels a bit more smoother, maybe a placebo though. There was way too much fluid in there, it's been topped up without pumping the brakes to get the level up... my fault. That will cause the brakes to lock in traffic under high brake use. Service lights reset at last too! The shaking under braking is intermittent, like it did when the lower TCA bushes were spent, they've been poly bushed now but there is clean paint on the arm by the drivers side bush of about 2mm suggesting the arm is moving about. Something to look at. I checked the rear diff level too which was changed not so long ago. Glad i did. Recently I've been getting a clanking from the n/s/r over lumps at speed. Knackered shock? Broken spring? No... I found the driveshaft outer cv bolts All loose! One had ever wound out! Good grief... Can you imagine... Checked the other bolts and they are all solid. Still, clanking noise has gone now after tightening the escapees up. The car has responded well to the recent work, quality service items and heavy use. It is time to start buying in spare parts though. AFM being one!

Sounds like you're well on the case, the vagueness / wobbly business when braking is also far too common, I changed my upper and lower front arms and it made a massive (I mean.. massive) difference, I actually have a spare set of upper arms (new, Delphi) which you're more than welcome to as I no longer have a six, these were sent in error and arrived a few days after the first set! I've probably got some other. It's kicking about too, if I find anything interesting I'll let you know.. these old beasts are bulletproof under the bonnet, all the issues I've ever really experienced (apart from the obvious perished hoses etc) have been from previous owners who, armed with a Haynes manual, have then bodged just about everything instead of actually fixing the issue! Anyway, good luck and let us know how the fpr and AFM get on.. for me the fpr was a game changer!

The worst thing is that Haynes didn't do a manual for it so even Bodgy McBodger had to use his brain! I'm still finding bodges and cut corners, there can't be many left though... All reasonably priced 635 parts are always gratefully accepted!
I'm hoping the shake was down to the over filled reservoir/ pressure issues as it is intermittent. When those bottom arm bushes had gone before, you could guarantee it would happen every time over 50mph, i cant even replicate it, it just does it when it likes... I'll find out on Tuesday!

'Sheer driving pleasure...'
A sales term BMW coined. This morning I set off early and took the BM. The sun was out, no winds and it was nice and dry and then during the journey I was faced with 22 miles of open duel carriageway...
After 31 years and 210,000 miles that car still has it... and does it very well. It's drives like these that make all the pain and suffering the other 364 days of the year worth it. It was 'sheer driving pleasure' and what's more, when I got out at the other end... all the bits bolted, screwed and clipped to it were all still there!

It's back with a vengeance... Jesus, give me some time to fix it! Tried to smash an Audi from the lights and it hesitated twice under full throttle... That's a new one. It's like it got switched off and back on again, the idle is low again too. Moving the car around at the weekend saw it idle at 400 rpm in drive or reverse. Eventually stalling. I still have to replace the fpr, mine is an obsolete unit, the spare I picked up is the more common unit, still, it means that the rail need to be changed too to mount it and my injector service kit has arrived now so I can crack on with that. I'm going to swap the afm eventually for an unmolested unit as someone suggested. This is a fairly common issue with a thousand solutions, luckily I'm through it by having replaced 867 items already. You know the real reason it's being like this? I spent Saturday cleaning and repairing the newly acquired green bmw, so it's bloody jealous! You wouldn't believe that machines get like this, what a curse word!
