I've been having some problems lately with the way my car is running. It's hesitating a lot at low rpm's and I checked the ecu codes and it came up as 21 something about the signal from the primary coil. Anyone know what it could be, my auto teacher said to check cap and rotor and their good and so are the plugs and wires.
