Cutting Out On Over-run, 1995 1.8 Petrol

[HarryS]

We have just acquired a ZX 1,8 which has an unpleasant habit of occasionally cutting out when coasting down to lights etc. It restarts immediately, or if the car is still moving can be bumped with it’s momentum. Whilst it’s doing this the yellow ecu warning light comes on, but goes out again.

The only other thing wrong with it is light pinking under high load, eg motorway hills. :huh:

 

 

My instinct says a failing engine management sensor, but which one?

 

Can anyone suggest what may be wrong?

Is it likely to fail completely and not restart?

 

Will a fault code have been saved in the ecu? If not, is there any point in getting it read?

Clearly we are not wanting to spend £100s on an L-reg!

 

Any advice much appreciated. HarryS, Yorkshire

 

 

Thank God its not a Xantia which loses nearly all of its braking if the engine dies!!! :P

Try cleaning the throttle stepper motor with carb cleaner which is located with the throttle housing by a couple of screws.

I had a similar problem with my zx 1.4 and after cleaning said part (which is attached to an electrical socket and after pulling out is of a bullet type shape!) cured the problem!

If not sure which component to remove try removing and cleaning any parts that are easily removable.

 

Hope this helps!

PS! I had a xantia and it was the best car iv,e ever driven! (I only let it go due to low mpg)

yep the stepper motor is a known problem item number 3 in the picture
