Could someone help please, for the last couple of days our 1998 Escort Gti has been trying to stall on tickover, when you first set out in the car it seems to be ok but after 5-10 mins in the car when you put your foot on the clutch the revs seem to drop right down and then appear to bounce back up, this will continue for a while and the revs seem to bounce up and down trying to stall then it seems to level out again, could someone please give me some idea what is wrong?

Many Thanks in advance

Sounds like your ISCV.

 

its prob going to be an air leak on the inlet side of the engine or poss the iacv needs taking off and cleaning out.

 

iscv all the way!!!!!!!!!

 

Will the ISCV need replacing?

 

You can try cleaning it and see if that helps.

 

most of the time you can get away with cleaning then out.

 

clean it mate, had this happen on my old GTi.

Give it a good spray with oil or something, that fixed mine

 

Many Thanks Guys,

Is the car driveable as it is or will it die on me, I wont be able to have a look until the weekend as I start my new job tomorrow?

 

wont cause any damage to drive it. may just stall at times

 

Just keep restarting it fella. It's a fiddly arse of a job to remove, and you'll have to do it from underneath. You should really get a new seal to be on the safe side..

 

Really dont want to sound like a dunce, but where is a the ISCV?

 

Under the inlet manifold on 1.8 and 2.0 zetecs.

 

its tucked away nicely under the inlet manifold and a bastard to get to......i just took the throttle body off,makes life a lot easier and a good spray/clean with WD40 sorted mine out.

 

Found THIS, might be of some help.

 

Thanks again Guys!!
