can anyone help got 2wd cossy when i start my car in morning with iscv on it revs to 3000 revs bought new one and it still revs to 3000 any ideas

 

tps faulty or mis adjusted.

air leak? does it do it with the iscv unplugged?

 

no runs mint with it unplugged

 

tps is most likley then, if the ecu spots a open throttle it opens the iscv.

check wiring,and base setting

 

Had a escort gti, and we changed the iscv and it made no difference, the TPS did the trick and it never did it again in the 2 years i owned it

 

cool its being set up on rollers this week will get it checked then thanks

 

is it ok when hot?

 

yes its fine with the iscv on when warm but if i come to a stop sometimes it it will rev hight but as soon as i unplug the iscv its all good

 

yeah prob tps....

 

Or a crappy chip, my EA chip did that anywhere between 1200-1500rpm when warm, now with GGR chip back in due to problems wiht EA one it is rock steady at 900rpm.
Mind you the AFR was 10.5 on the EA chip!!

i have got an ea chip but it was doing this before i had the chip fitted someone told me there is a relay that causes this aswell anyone else heard this or know where the relay is

 

A common problem or so it seems!

When mine did this it was a dead ISCV, replaced it twice, once with a supposed brand new ISCV and I still had idle problems, replaced it with a second hand item and it's pretty sweet and well behaved now!

Where did you get your brand new ISCV from as they are no longer made I don't know of anyone who stocks them anymore!?

 

NO relay involved with ISCV.
