Question about 2003 Kia Sorento
A misfire is not always caused by a bad plug or wire, although that is always the first place to look. I have found that this code is set by a faulty Defective Crankshaft and/or Camshaft Sensor more times than not. If the ciol ack does not solve your problem, then the sensors is where I would target next. But i am just going to say that I doubt that the coil pack will be your problem
Common Problems That Trigger the P0303
Worn out spark plugs, ignition wires, coil(s), distributor cap and rotor (when applicable) Incorrect ignition timing Vacuum leak(s) Low or weak fuel pressure Improperly functioning EGR system Defective Mass Air Flow Sensor Defective Crankshaft and/or Camshaft Sensor Defective Throttle Position Sensor Mechanical engine problems (i.e.-low compression, leaking head gasket(s), or valve problems
