Engine Performance problem
2000 Mercury Cougar 6 cyl Two Wheel Drive Automatic 114000 miles
I have a 2000 mercury cougar which has been great up until now. This problem has been going on for a few weeks and no one seems to be able to solve it. After driving about ten miles when the car gets warm it begins to surge and buck. I first thought it was the transmission and took it in to be checked. They told me they thought it was and engine misfire. I took it to another shop and they replaced plugs, plug wires, o2 sensor, fuel filter, belt on the water pump. It is still doing the same thing. I have since been back to the transmission shop and they still believe it is and engine misfire. I know that the fuel pump on this car was recalled. Could that be causing this? Please help I don't know what else to do.
have the same problem?
