That's not a bad idea...I took all the plugs out the other day and there was a little bit of oil in the threads of the plugs, but none seemed to be getting down to the plugs themselves. Nevertheless that's probably the culprit as I know the front valve cover gasket is shot anyway. The plugs and plug wires only have about 15k on them...not that this means they're brand new but they still look alright.
Codes I'm getting:
p0300--100% of the time
p0301, p0303, p0305, p0300--these usually show up 90% of the time
p0302, p0304, p0306--those are about 75% of the time
All these codes are consistent but it doesn't feel like the engine is missing very much. I don't really think it happens all that frequently, it just trips the code when it does happen. If it wasn't obdII I probably wouldn't even notice.
Basically it'll move around to all the cylinders but 1, 3 and 5 seem to show up more often. My uncle is a mechanic and I'm going to take it in to have him help me diagnose the problem for sure before I throw any more money at it. I've been running the car like this for months, though, so I'm pretty sure no matter what I'm going to have to replace the cat.
