How do I adjust my IACV 240sx?
Turn engine on and adjust idle screw. Your idle will be 50 rpm lower with TPS disconnected so shoot for 650 rpm to get 700 rpm. Make sure engine is warmed up and your base timing is at spec. Turn the idle adjusting screw on the IAA clockwise to lower idle or counter clockwise to increase idle.
Can a bad idle control valve cause stalling?
This is controlled by the engine’s computer. Sometimes parts go bad, which results in your car idling strangely or stalling. Check to see if your idle control valve is functioning properly before attempting to replace it. Look for a high engine idle. A common symptom of a faulty idle control valve can be a high idle.
What does it mean when your engine idle does not increase?
Use the command in the scan tool to increase the engine’s idle. 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.
How can I tell if my idle control motor is working?
Look for a difference in idle speed. Allow the engine to run for a minute so it settles to a consistent idle, then take note of any difference in the idle RPMs versus the idle you observed earlier. If the idle has not changed at all, it’s likely because your idle control motor has not been functioning.
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.
