i have a 1997 pontiac trans am, it hasnt been a week since the car head the blown head gaskets replaced and the heads resurfaced, when im at a red light or i stop at a stop sign, the rpm goes down to near half under one and im trying to see whats causing that, the service engine soon light would also start blinking and then when i leave the red light or the stop sign the light will stop blinking. So i was wanting to know the cause of that, and also will it be harmful for me to still drive it?
p.s. it almost seems as if it needs a tune up, but the spark plugs and stuff was replaced when i had the heads replaced, but i dont think the wires was, could the wires by the cause of it?
