2002 I6 5sp 135K miles.
I replaced the plugs right after I bought it. gaped to .035 (the originals were still in it an at .075
). New air filter as well. It did not miss or sputter then or now. I did not replace the coil rail. It looked in great shape. Finally cleaned the TB and IAC. It was NASTY!!!! I really should have taken a before and after pic. OMG!!! Put it all back on and it still wants to idle at about 550-600 rpm. I thought I saw the spec for it was supposed to be 900 rpm. Can anyone confirm?
What am I missing. Runs great and no issues. I did disconnect the battery while cleaning the TB and hooked it back up. Would I expect the computer to relearn and bring the idle back up?
