so it s working fine this afternoon all the way home from the shop, its a PW0 by the way, but when i left my house this evening to go see my lady i got a "check engine light". here is the part that is confusing me. when i press in on the gas the light comes on. when i let off the gas the light goes out. when i press in on the brakes the light comes on, when i let off the light goes out. anyone know what in the hell is going on ?
