my car jugs when i put slight pressure on the accelerator, its fine when i got my foot right down or half down maybe quarter but below quarter it jumps and jugs like its struggling, someone said could be the adjustor on the clutch what do you guys think?

 

U say uve got a problem when you accelerate less than 1/4 throttle and someone has suggested the clutch

 

What car is it ?

Could be throttle position sensor if you have one, they tend to wear out and the reading off them is inaccurate in some throttle position, leading the ECU not to know how much fuel to put in - hence the erratic running.

HTH

 

thats what i thought, how can it be related to the clutch, yes whatever hear im in it seems to not pump petrol in at that point on the accelrator, well it does but jumps really bad so i cant cruise really slow in traffic coz it just jumps, how much would it be to repair the sensors ur talkin about

 

Tell us what car it is first give us a clue

 

o yeh soz lol, well the engine is a 95 escort zetec engine 1.6

 

The way you worded that im presuming the engine is not in a 95 escort then no?

 

no the engine is in a mk5 94 escort

 

Hmmmmmm well i was going to say if it was in something foreign there could any number of possibilities. Was it a like for like swap or has the car been converted?

 

no the engine was converted in 2001, and its only just started doing it yesterday

 

Hmmmmm see being a conversion there is so many possibilities, even harder when someone else has done the conversion simply because you don't know whats been done and what hasn't. I'm not really up on Zetec managment either haven't really come into contact with it much, but theres always the usual MAF sensor and Throttle position sensor faults that could crop up. Might be worthwhile get a diagnostic tester on it.....

 

diagnoster test, cool, where do i go for that, is it most garages or just some, and does it cost?

 

Hmmmm i dont know what dealerships would make of doing diagnostics on it if its not an original car, might be ok. I'd try and find some with a tester or try and borrow one or something. I can't be overly helpful on this as haven't had chance to play around with any diagnosable management systems yet

I'm sure someone else will spot this post who can give you some more advice

 

Sorry, can't help any further, I don't know that engine at all

anyone ?

 

dunno if this helps any1 understand what the problem is, but as im de accelerating the car backfires well not so much of a back fire but alot of popping than usual from the back

 

My RS turbo had a problem like this - juddered under light throttle but not when you booted it. Changing the spark plugs cured it for me.

 

I still think a diagnostics check
