1993 Z28 trouble codes My car has a new code. I found that out today an its code 22 which means wide open throttle circuit grounded but i haven't noticed anything, because when i left autozone i mashed it an it opened up. I just recently hooked up a CB radio for my car that i hooked the positive to the battery an the negative to a ground spot infront of the battery. Last night it was idling high around 1100 usually idles 900 or so. It quit idling high but anyone know what this might be.
