pvc valve is good, got a po320 code from scanner, so im thinking maybe the coil pack is bad since it is distributerless

Replying to: wizard43 (Jun 22, 2009 5:05 am) From a website: A P0302 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #2. A code P0302 may mean that one or more of the following has happened: Faulty spark plug or wire Faulty coil (pack) Faulty oxygen sensor(s) Faulty fuel injector Burned exhaust valve Faulty catalytic converter(s) Running out of fuel Poor compression Defective computer Possible SolutionsIf there are no symptoms, the simplest thing to do is to reset the code and see if it comes back. If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors. My Comments: I would pull all the plugs and take a good look at them, note the color of the innner ceramic insulator and gap. The ceramic insulator should be a light tan color to light brown. Dark colors means that cylinder is not firing well, which could be due to the spark plug wire bad, coil bad, injector bad, clogged or dirty, oil flouling, ect. If you find one or more dark plugs, investigate everything associated with that cylinder, and gap all plugs, replace plugs if needed, replace wires if needed. Also check for air leaks, as an air leak can cause the engine to run rough and die. Check the Air bypass valve located near the throttle body, it has two wires going to it, sometimes they get clogged and stick and let too much air in at idle. Cleaning them will fix them most of the time, otherwise replace. Will your engine run OK if you rev it up? If so, it may be an Idle problem realated to an air leak, egr valve, Air bypass valve, etc. It the engine runs rough at idle and rough at speeds over 1500 rpm, it could be an ignition or injector problem. E.D. |
