I checked all my fluids in my car but my service engine soon light keeps coming on. I reset it twice it usually pops on when I put my foot in it..the car still drives the same know loss in power but that light is irritating...any ideas(2003 ford mustang gt)
O2 maybe. My car did the same only when I drove hard. I only had the car for about a week. I thought the gas cap was bad and not keeping pressure. I later learned the cats had been removed and the 2nd O2 was giving codes. I was initially told the cats were stopped up, but after lifting the car I saw all the cats had been replaced with a straight pipe. I used Plug-In MIL eliminators from AM to solve the problem. Happy customer!
