Coil on Plug or does it have plug wires? Having plugs in bad condition (or wires) creates excessive resistance in the ignition system and that resistance causes the coils to overheat. This overheated is the main cause of premature coil failure.

If you have a volt/ohm meter, you may want to first ohm check the resistance between the two spark plug towers on each ignition coil pack. Simply remove the spark plug wires from each coil pack and test. Both (if good) should test about the same resistance, (about 5-7 kOhms, but I don't have the exact specs handy on this particular vehicle. The reading may be higher, maybe around 7-12kOhms) but nonetheless, the reading of the 1-4 coil pack should closely match the 2-3 coil pack. If not, the new coil pack may be faulty and should be returned for a replacement.

Also, when you remove the 1-4 coil pack, take a look at the primary spade connectors (2 lugs) coming out of the ignition module. Make certain these are clean and free of rust or corrosion. If so, simply (and gently) use a finger nail file or 400 (or equivilent) sandpaper to file the corrosion off and re-attach the coil pack.

If one or both of these don't fix the problem, you may have to look at replacing the ignition module. But only do that after exhausting the other simpler and less expensive tests! :)

I hope these tips help you out or at least point you in the right direction! :)

it is always a good idea to stay with o.e.m parts and yes there is updated parts in the newer coils. and yes the M.A.F will also cause misfire faults but will not make check engine light flash or make car shake and shudder. also check you wire harness going to your coils make sure your ground wires are not cracked. That could be the main culprate. good luck hope this helps

I have a 2001 toyota fourrunner showing computer codes p-0300 & p-0304. What are these codes for?


The P0300 is a random multiple misfire code, the P0304 is specific to the number 4 cylinder, a common problem for this code is a igniter/coil malfunction on the #4 cylinder, each cylinder has it's own coil, what you can do is to remove the #4 coil pack(it's the middle one on the driver's side) and switch it with coil #2 which is the first one on the driver's side, clear the codes and drive it if the code now shows P0302 replace the coil.
