Cleaned throttle body, replaced air filter, replaced IAC. Reconnected battery, let car idle for 10 minutes. Car is driving fine. When I start the car, RPMs jump to 2000 and rest at 750 when in park. Just wondering if this is normal. Thank you.
Throttle position switch maybe bad and some can be adjusted. Google that question and the year , make and model of your vehicle and it will take you to a site that will let you know if you can adjust the throttle position switch on your vehicle
