K11 micra cutting out when hot, and randomly.

[markbognor]

I've been having some issues with the engine die-ing recently. These episodes have been predictably unpredictable. Though a couple of times I have had a repeat of the same issue, when starting from hot the revs pitch and drop, and any load on the engine will kill it completely, any throttle with make the pitching and dropping worse, but it will only rev to around 1500 before dropping again. I have replaced the very unpleasent looking fuel and air filters, and there's a dizzy cap and rotor arm to go on. Cleaning the fur off of the contact points in the dizzy and rotor tip seemed to have solved the problem, until a couple of days later when it started again - so I'm really hoping that the new cap solves the problem. But secretly I'm pretty sure its some of the black magic electrickery that keeps everything ticking along nicely until it decides to throw a wobbly.

So when the dizzy cap fails to solve the problem, what do you reckon I should try next?

TDC sensor and loom?

I've fitted a lot of new (S/H) dizzys to these for local take aways, starts off with random hot cut outs then gets worse and usually ends up with me towing it back and replacing the dizzy.

Running on light throttle only, and stumbling/dying under load but revving a little better when in neutral were the symptoms I had with weak spark from a failing coil. Next time it starts doing this it might be worth pulling a plug and checking to see the condition of the spark. Once you know if spark is the problem or not you can try dizzy or leads or coil or whatever

New cap and rotor arm - nil points. Left it running for a bit before lunch, turned off, wait a mo - turn back on - starts faultlessly but then wont rev - when held at part throttle the revs lift and die, and bit like I'm tapping the throttle and revving the engine, but with the pedal stationary.

Just like it did yesterday when stopping at the supermarket after the run into work, and last night at the motor factors after coming home. By the time that I had limped back through the estate to home, it seemed to be running fine again.

Could be the coil be playing up when hot and then once the car is moving a little be just enough to cool down and work properly again. Which is built into the dizzy - tieing the fault up with bortaf's fault and remedy - down to my nans I think to take the distributer off of the tourquoise car.

sounds like dizzy,.

If it's the same as the ones I've had in the coil is in the dizzy and it's easyer to just change the whole lot from a breakers ?

100% dizzy related mark probably the hall sender in the dizzy playing up had this problem before is the dizzy getting really hot when it cuts out? guarentee it will be this common fault
