Hi ime after some help on how to adjust the idle on my zetec turbo engine. The engine is running pectel t2 managment and a cosworth throttle body, the engine is idling at 2400 and want to set it to 900, I have tryed to adjust the idle screw on the body but it hasnt droped even though its all the way in and i have disconected the throttle cable aswell just incase that is holding it open slightly,is there any thing else I can do to lower the idle? Or will I have to have it remaped as the whole engine spec has changed since it was last maped

 

check for airleaks

 

Already checked for them and cant find any

 

does it use the cossie iscv?

 

Yeh its got a brand new cossie iscv on it,

 

has it always idled fast or just started doing it?

 

It use to be ok but since then I have changed every thing on the engine including the tb, wouldit need a remap to lower the idle? I know ihave to get it remaped but wanted to get it running ok amd any leaks and issues sorted before then

 

does unpluging the iscv do anything? have you got the correct tps required for your ecu?

 

Havent tryed unpluging it, will try that, the car was originaly mapped with a frst tb with standard frst iscv and tps

 

thats gonna be the problem then,AFAIK your ecu will need reconfiguring to the cossie stuff if your ecu gives these options.

 

Thats what I was thinking, looks like I will have to get it remaped

 

mapping will sort it rob, its running then

 

Yeh its running now jon been trying to get it finished for castle coombe next month, but I dont think the car wants to go though, nothing is going to plan lol

 

hope to see it there!

 

So do I lol, still got a few bits to sort then a mot, but if I cant sort the idle out it wont be going
