What should idle speed be after camshaft change?
There is no reason to simply increase idle speed from 800 rpm to 1,000 rpm after a camshaft change when a little extra calibration time allows the engine to be stable at 850 rpm. Careful control of fuel delivery, airflow mapping, and spark compensation are the keys.
How can I check the idle speed of my engine?
A final check should be made to verify that commanded idle speed in the PCM matches actual engine speed and that the IAC is near the middle of its range. During idle speed calibration, it is helpful to monitor data in real time for MAF, MAP, lambda, injector pulsewidth, and temperatures.
What to do if your car is idling too fast?
A throttle body cleaning is likely to cure the high idle speed as well. There are many possibilities when your engine is idling too fast. Here are some common ones to help guide you towards the root of the problem.
What can I do to make idle speed more stable?
Reinstalling the IAC harness lead should result in a more stable idle. This prevents the IAC from leaning to either a fully open or closed static position. The object is to get the IAC motor in the middle of its adjustment range so that it has maximum flexibility to adjust airflow either up or down.
How can I increase idle speed in a Chrysler?
If the resistance is outside that range, the idle control motor needs to be replaced. Use a bidirectional scan tool to increase idle speed in a Chrysler. Connect a bidirectional scan tool to the same OBD port you would plug a code scanner into. Use the command in the scan tool to increase the engine’s idle.
How can I tell if my idle control valve is working?
To check if an idle control valve is working properly, start by turning on your engine and letting it run for a minute or 2. Then, when it’s at an idling speed, take note of the RPMs in your car. Next, turn the engine off and disconnect the idle control motor under your hood.
How to troubleshoot an automotive engine high idle?

What does it mean when idle control does not increase?
If the engine idle does not increase, it means there is an issue at the idle control motor of its circuit preventing the signal from changing the idle. You can purchase a bidirectional scan tool at your local auto parts store. Make sure the wiring harness is firmly connected to the idle control motor before conducting this test.
