I installed a MPx downpipe without a cat this morning. I drove it around for about two hours and the power difference was incredible. My engine check light came on after about 2 hours of driving. I stopped at a stop light and upon it turning green, I had no power. My car could drive, but I couldn't accelerate at all. I was a turtle. When I put my car in neutral/push in the clutch, I can rev like crazy. But if I'm in gear and I try to go, my RPMs go up so slow and I accelerate like a handicap cart in Walmart. I THINK I blew my o2 sensors... But I don't want to be buying and replacing things if I don't know for sure. Any suggestions?
