Re: 89 tbi running & starting problem

Ok checked the TPS and re checked the IAC both are good. I did disconnect the map sensor and the truck didn't change the idle at all. When I did fire it up today it ran smooth but when I mashed the throttle it almost died till I let off, but when I did it again had a nice fire ball as it back fired through the throttle body. "On a funny note it scared the crap out of my buddy that was over!"
