Just recently I made the move to Florida from Ohio. Ive been down here for about 5 months and suddenly my car jerks real bad when I accelerate. Its does ok when you lightly touch the gas pedal and speed up but when you push on the gas pedal as you normally would thats when it has the problems. When you give it more gas it runs smoothly. It jerks when you take off, then at around 30-35mph and again at about 45-50mph. I have changed the o2 sensors, plugs, wires! Im not sure how to test a coil pack with a multimeter, or if that could even be a cause!? Please help me! What could it be?
