danadak426 Posted June 18, 2007 Share Posted June 18, 2007 1992 Accord EX, 58K miles ... turn a/c on, idle comes down to appx 400 rpm when in gear ... does not stall, but vibrates, etc. How do I diagnose this/what might the problems be .. ? Shouldn't idle come up with ac/ on? Thanks! Link to comment Share on other sites More sharing options...

Kastigir Posted June 19, 2007 Share Posted June 19, 2007 Unless the car is stalling you should be fine. Have you checked your motor mounts to deal with the vibration? Link to comment Share on other sites More sharing options...
