so I have searched.
most people have the opposite problem I have.
if I start my car, it idles fine. then drive it around till operating temp and the idle will go from 1000 RPM down to maybee 400 or so almost die and go back up to 1000RPM again over and over again.
here is what I have checked,
intake tract = no leaks detected (even used the smoke machine at work)
cleaned MAF
cleaned throttle body best I could
coolant is full and norm operating temp is maintained
o2 sensors read good using a scan tool for data monitoring.
my question is..... is this the symptom of a IAC or more of a TPS sensor.
i am leaning towards the IAC because if I just crack the throttle it will maintain 1000RPM as long as I hold it.
let me know
thanks
