today i took the car to autozone cuz the cel was flashing. and they told me that cylinders 3 and 4 were misfireing. so i am going to replace the wires and plugs. now the shakeing is not the tires cuz i took the tires from my contour and put them on her car and it still happend. my car dont shake. i am thinking cv joints also. and the catalyc converter is pluged up so that could also be why it is so slow. i dont know if it could make the car shake. o and if i cut the catalyc converter off and replaced it with a stright pipe. would that be leagle. someone said it is not. i dont know i will try to figer it out i will let you know if i need help. thanks.
