Hi
Just gone to level 8 and light blues on my 3dr, have changed the TPS and swapped the wires and the car starts and runs perfect.
One small problem though, every now and then maybe a couple of times a week when I start it from hot the engine idles at 3k. If I just turn the key off and straight back on it returns to its proper idle.
Any ideas?
Thanks in advance

 

I would say it's down to a sticky idle speed control valve. Remove, soak in a little petrol to clean. Replace & all should be OK. Failing that replace it with a Known good one.
Regards

Yeah def sounds like the ISCV, mine does it very rarely sometimes but i have yet to take it out. A good boost normally sorts it out for another few months

 

Thanks
I changed the whole throttle body and ISCV at the same time, so I think I will swap it back to the old one that i know was OK.
Cheers

 

Did you set the idle up once warm and co ??
