P0300 and P0302, HELP!

Check the coil/plug connection.

MAF problems will (usually) affect the whole bank, not just one cylinder.

Dealer could possibly refuse warranty on your suspension but not other items that haven't been modified.

Thanks man, already checked the connection several times, didn't help. Spark plug I removed smelled heavy of fuel though. Would that mean I have to change the other plugs and coilpacks on the same bank?

That sounds like the plug is still not firing. Check the primary side with a VOM (may take a sensitive meter to see the quick pulses) and make sure the coil is being pulsed. FWIW, the plug fires when the coil is de-energized.
Not sure how you can check the secondary side. Back in The Good Ole Days, we just laid the spark plug on the block and looked for a spark.

It sounds like it is only the one cylinder messing up, so the rest of the bank is probably OK.


You may have a fuel injector problem.
