I've changed the spark plugs and 1 coil, crankshaft sensor. After all that car drives worse. When accerating the car jerks and hard to get to 40mph. Could it be a camshaft sensor and do you if there is more than 1

Need to remove your spark plug coils and see if there is a crack in one or more of them. If plugs are installed too tight they will hit the piston and crack down the length of them, so look closely.
