Question about 1999 Chrysler Cirrus
I replaced the timing belt and water pump on my Cirrus. After reassembly, the engine runs at 2500-3000 rpm at idle. The throttle cables are not sticking, and the fuel pressure is great. What could cause this?
The throttle position sensor may be misaligned. This tells the computer how much throttle is being applied, and when they go bad, or come out of alignment, the idle tends to get up there. If that's not the issue, remove your air cleaner, the housing and everything until you get to the MAP sensor. Give it a good spray with carb cleaner, let it dry and replace the air cleaner with a new one. If the MAP sensor detects minimal air flow, the computer jacks up the idle to compensate.
