high idle

[tl14910]

well i just started my car up after removing the a/c and putting a new thermostat and radiator, im getting a real high idle (2200-2400rpm). anyone have any ideas as to where i should start diagnosing this problem? Thanks for the help.

Sounds to me as though you either forgot to connect a major vacuum line, or you unknowingly ripped a vacuum line.

I'd start there, searching for a vacuum hose that's either off or broken.

OR... did you disconnect the battery while performing this work? If so, it is possible that the chip "lost its marbles" & just needs some drivetime to re-learn.
