MY CAR IS STILL RUNNING CRAPPY PLEASE HELP MEEEE!!

well last night chummmmmmmaa came down and scanned my pos car, was showing alot of misfires from cyl 4. 6 was showing a couple but not too bad. actually i think that whole side showed a couple here and there. the other bank was at 0 most of the time. anyway the coil packs are good, we swapped them around, they were fine. new plugs, correctly gapped, new wires too. but stilll misfiring like hell. no other sensors threw codes. just that damn P0300 code. we checked the pushrods, they were ok.

another thing i noticed was that the intake runner going to the #4cyl was hot compared to the rest of the others.. wtf?

so im gonna do a compression/leak test tonight

my thoughts before that test--

bent/stuck/burnt valve?
bad lifter?
timing chain skip a lil? only 49k miles on the motor.
