Whenever I'm driving around and I pull out of gear or disengage the clutch, it seems like it takes forever for the idle to settle down from around 2Kish RPM down to around 1Kish.

I tried to fix this with some stuff I read about from RBob's notes on IAC logic "To reduce flair-up on engine start:

Lower the park position @ 0x5C2.
Lower the park to run delay @ 0x5C3.
Lower the kickdown time delay @ 0x5D7.
Lower the coolant vs. position values @ 0x5F5.


To quicken the return to idle after throttle blip:

Set delay @ 0x5E7 to 0.
Increase filter coefficient at 0x5E4.
Reduce throttle follower percentage @ 0x5F0 & 0x5F1."



Not sure if it helped really though....

Here is the original thread http://www.thirdgen.org/techboard/di...-follower.html from the prom tuning guidebook on TGO



What do I need to do to fix this?
