Whenever my car warms up after driving a couple of minutes, the car begins to sputter when I push on the pedal to accelerate. At times, it will sputter a little without pushing the pedal to accelerate. I have replaced the ignition coil (3 of them), valve cover gasket, plentium o ring seal, sensor oring, cadilac convertor - all in the last week, but I still have the same problem.
Could the issue be the throttle? Or could there be other issues causing the prsputtering? Please help, thanks.

When you replace one of the coils on this car you have to replace them all. You may also want to replace the spark plugs while you are in there. On the passenger side valve cover check the PCV tube that goes to the throttle also. Pull it off while the car is running and cover it with a rag if the sputter goes away clean out the port, tube, and if at all possible run a throttle body cleaner through it. Daytona Air Induction and fuel system service have been the best Ive found so far for this problem. These are very common problems in this car and the lincoln LS. Same car.
