Hello. The first task in solving this problem is to extract problem codes that are set, whether the Check Engine light is on or not. There are several problems which could cause this behavior, such as a bad throttle position sensor, fuel supply issues (low fuel pressure), or a dirty or bad mass air flow sensor. Problem codes will narrow the cause more quickly, and help avoid replacing parts that are not the problem. If you need to have a certified technician from YourMechanic can come to your car’s location to diagnose the gas pedal problem and follow through with repairs.
