I just recently changed out my catylic convorter and my car still will not take off. The problem is that when i gas my car it seems like something is restricting it from going. But when i let off the gas the car takes off. My fuel pump is fine and the fuel filter is fine. Cap and rotor ok. Anyone have an idea on whats causing my truck to not take off? Also the MAF is ok.
