Idling and gear problem

Check your TPS to see if it is set correctly, and another thing have you reset your ECU after all these changes.

Have a PFC. Not going to reset that.

Hi all I have a idle problem from cold start. Wants to rev a 2k rpm until warm then OK with some hunting on occasions. The AAC is fully adjusted in and still revs high. Has happend since new turbo, plenum, throttle body fit up and yes above 20psi boost on occasions. May it need a clean or new diaphram or even the HKs idle stabilizer. PFC temp/idle settings seem OK.

Thanks

It's supposed to rev high when cold (but maybe 2k is a bit high).

The AAC should only be adjusted when the engine is up to operating temp, and you need to disconnect the electric plug first (otherwise the ECU will just keep making adjustments, countering your adjustment).

If it still revs high, check the position of the TPS, that it is closing properly and sending the 'closed throttle' signal to the ECU.

Do you have an Air Box or a Pod Filter??? Sometimes a Pod filter can cause the car to run REALLY RICH....

my idle isnt very steady. the afm is to blame... TRy tapping your afm and see if it affects the idle.
