yep thought that to.Changed fuel filter today.No luck.1 st gear pulls hard and normal 2nd sometimes does it but 3rd gear right at 4000RPM all the way up to 6000red line then shift to 4th mash the gas same thing,skipping and jerking but still climbing in speed but not as fast as it should. Wires were changed recently.Dont see that the plugs were.Just bought the car so trying to establish a baseline.
