Engine Performance problem
1994 Chrysler LHS 6 cyl Two Wheel Drive Automatic 199000 miles

My LHS has a 3.5 engine and won't come down to slow idle? It does step down to 1600 rpms only. Just started this. There is power to Idle motor unit.

Hi orrkid, Welcome to 2carpros and TY for the donation

Clean out the idle air control motor air bypass passages and make sure the IAC motor is retracting, check for vacuum leak and test the throttle position sensor voltages idle and wide open throttle-see below specs
