1997 blazer idles too fast,1000 RPM in park. 2000 rpm in drive. I have changed the idle sensor and the MAF sensor. Also installed a new throttle body seal. Problem still there. HELP! (310,000) on engine.

Re: idle problems
Does the Service Engine Soon (SES) light work? If it does, what are the Diagnostic Trouble Codes (DTC's) in memory?

Re: idle problems
Does the SES light come on when the key is turned to the RUN position and go off after the engine is running?
