i am driving a 98 mustang Gt with a flow master exhaust system, there are two cats took off the car. The check engin light is in and the car spudders when you floor it. Does anyone have a idea what is wrong with my car
Could be a couple of problems. CEL could be from there being no cats an no CEL eliminators installed. Sputtering could be from a number of items related or not to the CEL. Checking on the existance of the eliminators, then getting the codes read is a good place to start.
