96 SPI

Recently and intermittently i have had some sort of problem with accelerator sticking. Its not the actual pedal which sticks, but it feels like even when im not accelerating the engine is still revving, at a constant rev. it normally happens when decelerating from speed. and the car doesnt seem to slow down as quick!

Also when waiting at lights with my foot on the clutch the car is revving more than normal it seems to idle at around 2 on the rev counter.

This does not happen all the time!

The times its happened I have turned the engine off and restarted and normal service is ressumed.

It all seems very odd to me! perhaps unrelated I am about to change to the engine steady bushes as i can here the engine creaking when accelerating or decelerating , engaging the clutch etc. I thought that this was caused by the engine steady bushes being worn but it may be related to the above problem.

Thanks in advance for any help.

Cheers.

Although i am pretty clueless! After a quick google search i seem to have narrowed the problem down too either (but what do i know)

"air cleaner air temperature control"

"inlet air temp sensor"

The problem only really occurs after driving on the motor way : I assume it must be somethig to do with the engine running warm and one of teh above sensors /systems no functioniang as they should.

Another possibility may be the throttle body.

as i say i just googled around and found this info, so i could be way off!

Help much appreciatted!

i had a similar problem on the scamp and all it turned out to be was the throttle cable was caught behind some bits in the engine bay causing it not to more freely in the sheath.

another possibility is the fuel trap is blocked as its an injection model. i dont have pics to hand but if you do a search, there are step by step guides about how to clear it.

Thanks for that!

OK sounds totally feasible it could be the throttle cable! howver it looks clear! and revs fine when i checked over today.

It is gonna be one of those problems that you need to catch in the act as it where! I could take it to a garage but whos to know it will present its ugly head while there?

As I mentiond I need new enginge steady busehes soooo the excessive movement of the engine could be provide some sort of obstruction to the cable sometimes. OR?

Any other ideas out there? its a bit unsettling when the car wants to drive itself. A gear change or popping the car into nuetral soon stops the excessive reving !

Post up in the 'injection' section - more likely to get answers there! Could be stepper motor problem - or bad connections - but the 'injection' lads will know!

I have the same problem recurring every so often on my '92 spi and found it to be a problem wit the spacing of the lost motion link between the throttle cable and stepper motor. If you have a haynes go to section 4B.4, shoes you how to adjust it. Works for me, for a while anyway!!

I'd be interested to know if anyone knows how to sort this completely as doing it every 3-4 weeks is a pain
