Q: check engine light on and racing engine

asked by on

Check engine light just came on and engine is racing

My car has 85000 miles.
My car has an automatic transmission.

You will need to have the Check Engine Light tested and the codes diagnosed to find the cause of the high idle. Since you say you are experiencing a racing engine, you may have a bad throttle position sensor or idle air control valve. Only the test can reveal the problem and isolate the cause. If you need help with this, a professional technician from YourMechanic can diagnose your Check Engine Light and make any necessary repairs or adjustments.
