So my 1990 firebird formula occasionally likes to give itself gas. the check engine light comes on and with me not pressing on the gas it goes to 1000-1500 rpms. I've gone 30 mph without giving it gas. the way i stop is putting it in neutral it usually happens when the car is warmed up for awhile and when i turn off my car when it is warm then turn it back on in like 10 minutes. I know I could hook up a code reader but I just wanted to check here for some ideas

Could be a couple things, paper clip a/b method to pull codes.

Okay thanks .. I gotta remove some of the plastic to fit my code reader in there for some reason
