Hunting problem :o(

[antrosser]

Hmmm ok, hopefully that will fix it :o) Is it the throttle position screw you need to adjust to control where you want the car to idle at?

Altho it still hunts when the idle control valve is off?

TPS, or air leak.
 
More than likely TPS. When the car is cold the TPS voltage is high enough to make it idle nicely. Once warm the voltage drops and then you get your hunt problem.
 
Check TPS with the sensor check page found in the ECT section on the PFC hand controller. Look at VTA1 and VTA2. VTA1 should be between 0.75 & 1.25 when the car is at full temp but off. Throttle in all the way and it should be 4.0 or more but never higher than VTA2 or on 5.0
 
Check these, adjust if need be then let us know. If the problem continues then we can move on to something els. 1 problem at a time.

Cheers for the input Nikp disconnected the Idle control valve, and it is working fine :o) no more hunting problem!! Also the idle is alot lower at around 1k where as before was about 1250!

I love these websites as every one is so friendly and willing to help other members out :o) so thank you all!!!
