engine light idles high

Hello to all. I have a 1997 cavalier the check engine light is on I had it scaned at a dealership and it says the car is idleling higher then expected I have checked for vaccum leaks, replaced the throttle position sensor, and the idle air control but the light stays on even though I have driven over 50 miles any ideas?

disconnect the neg battery cable for at least 10 min and then try it, that should clear the computer.

thanks but it keeps comming back

Check for a vaccum leak somewhere... Could also be your IAC.

Ussually a vacuum leak cause lower idle and makes like it wants to stall out.
