Shakes or Wobbles problem
2003 Pontiac Grand Prix 6 cyl Front Wheel Drive Automatic 136000 miles
My Grand Prix recently had the water pump go out. I changed that with no issue but now the car is shaking. It shakes at idle while still, the moment just before a stop, and when letting the car go forward without foot feed input. In park the shake goes away around 1500 rpm. While driving there is no vibration/shake whatsoever and it drives like a dream. Full power is there with no cutting out. It did kick a code which was for misfire in cylinder 3. I changed all plugs and wires and #3 is still kicking the code. The codes are always pending when read. I switched coils hoping the misfire would move with the coil but no, still #3. The shaking can at times be pretty strong. Along with that shake it has an exhaust chug keeping time with the shake.
have the same problem?
