The car jerks when accelaring espacially between 45 and 55 mph and when it is cold. The check engine sign is on and flashes when the car jerks. The coils, sparks plugs and ignition wires have been replaced, but the problem persists. The code was 340. I'm worried that the problem might cause more damage to the car. Does anybody knows what could that be? Thanls
