A friend of mines car dies down when you hit the gas too hard. It starts up fine though. I think its a 91 convertable. Im into first gens but i thought ide help this guy out and take a look at it. First thought that came to mind was the 5th/6th ports could be stuck but im sure there could be some other reasons for this bogging down ordeal. Any info at all would help me out. I hate to see a great car sit! Thanks you.
