Random Cutting out!

[e30kid6]

Hello

The car '88 318i.

It has caught me quite a few times now. But the car just randomly cuts everynow and again. Its okay if ive got some momentum because it bump starts straight away but it sometimes takes a few minutes before key start works. For some reason the revs just seem to drop mainly only when changing gear but has happened when accelerator is down. Ive recently had a broken rotor arm and distributor replaced, injectors cleaned, and new gaskets etc.

But the problem seems to get worse and then not do it for a day, then gradually get worse again. I have been advised to check one of the relays in the engine bay (controls something to do with timing of the spark)? Could anyone give me a couple of pointers?

Thanks

When you say key start works, do you mean actually turns over or actually starts?

I suspect CPS sensor. . .

It will turn over fine, just fails to fire for some reason. But it sometimes starts straight away, sometimes take a couple attempts and once it took 10 minutes. :s

What is this CPS sensor?

cheers

The Revs drop immediately to zero but the warning lights take a few seconds to come on and same with the steering losing power.
