What would cause this? I decided to pull my cels today (the light is always on due to tranny swap) and got p0300 all the way to p0304 .. I've done spark plugs and wires about 10k - 15k miles ago. Would it be a cap and rotor problem ? Anything I should check ? The car seems to be driving and starting up fine.

Since it's all i'd say possibly consider to change the cap and rotor, and run some fuel injector cleaner. If you used plain copper plugs last time then might as well change them again.

Had a similar problem with my car turned out to be a problem with the ecu....try unbolting the ecu and wiggling the plugs around while the car is running and see if that changes anything

Ya know, I cleared the codes and it hasn't come back since .. I don't really understand what that means, but I think it's about time to do a cap and rotor change anyways ..
