if you have fault codes, or an idle that high the relearn generally won't be accepted so the adaptations will not be met.
with the idle that high and a new throttle you might need to find the air leak before going any further. Smoking the intake is the easiest way to go, but seal the throttle opening first.
does your 02 have the electronic throttle?
nevermind i pulled it up, yours is the 2.5 which had the electronic throttle. The 1.8 still had the cable driven this year model.
With these electronic throttles there is not alot of things that will cause high idle. It's usually the Throttle body itself (when the idle is high and fluctuating up and down) or the APP sensor (pedal). When the idle is high but more steady then it's usually because of an air leak close to the throttle.
sounds like the pedal position sensor. Do you have a code for it?
it would be an APP code.
yea, if you have an app sensor code replace the gas pedal its electronic. should have a sweeping voltage increase when depressed. They are relatively cheap around $50.
as far as getting the relearn to take, if you have disconnect an injector or 2 to get the idle down then you can temporarily.
if the pedal voltage is in spec and your getting no response, then the signals at the throttle need checked to see if the ECM is interpreting the signals from the pedal to the throttle.
