Low Idle

[pandaman]

since changing the idle control valve on my gtr it wont idle higher the 500-600rpm

adjusting the aac valve has no effect.

any ideas?

my guess is that you need to lock it into base idle mode otherwise the ecu will continue to regulate the idle to where it is now no matter whan you do to the idle screw.

do you mean redoing the PFC idle procedure?

I have exactly the same problem, re-did the PFC idle procedure but nothing..

ok well saying that you had an aftermarket ecu to start with may have been a good idea, LOL.

when you say that you have adjusted the AAC valve, are you talking about the idle screw? or is there a setting in the PFC that can adjust it? i'm not too familiar with the PFC.

redoing the idle procedure may help, otherwise there may be something in the settings in the ecu that needs altering.
