hey can any 1 shed some light on the fact my car wont idle when cold i recently replaced the idle control valve as it was hunting a lot on tick over! now it ticks over about 750ish rpm now that has stoppped but wont tick over now an if when driving revs drop a bit low its hesitant before its picks up i have looked/chaecked for vacum leaks etc all advise welcomed

 

have you access to a monitor? (pectal, collins, etc) tps setting can make a differance.

When was it last set up?
