I've had an misfire and occasional stalling with my coupe for a few weeks now. It happens first time, every time when I run the car and I've gotten into the habit of selecting neutral (it's an auto) when I stop in traffic because it will almost certainly stall.
A couple of PeachParts threads suggested that the root cause of this sort of problem is cheapo rubbish HT leads so I thought I'd have a look.
They are the el cheapo Beru parts that everyone said were rubbish.
I could also see that they were all over the place inside the channel. I did a bit of tidying up, clipped some of them in where clips are present and fired it up.
No misfire. Left it for a bit, it didn't stall. Shut it off, started it etc. Many repeats. No misfire and no stalling.
When I put all the covers back on it obviously squashes everything back in and brings the problem back.
The covers are bulging all over the place and the front-most clip is actually broken off, presumably from someone trying to squash it all in.
I've done a bit more jiggling and have got it squashed in, secured, and have done more testing so I'm all good at the moment.
The photo below shows the leads coming into the channel, is there an insulating strip missing from my engine here or is it cool that they're on the engine?
It also shows one lead that I've had to double back to shorten it while stopping it resting on the engine.
The coil supply was routed so that it hugged the engine under the curve shown below and is a bit melted as a result. I've moved it away and secured it so that it won't move back.
I think I need new HT leads but I'm not sure if I can do a rescue attempt by correctly routing and securing the current set.
Waste of time?
Would an OEM set, rather than these Berus, be correctly lengthed to avoid doubling back and taking up too much space?
Does anyone have a guide to routing or an example of a well routed set of HT leads for the M104 engine?
