Misfire!!! When i bought my car it had a misfire, (p300 code, random multiple cylinder misfire) so i replaced the original cap and rotor with a msd unit. after this didnt work i decided to change my plugs and wires when i did my headers. the scanner says it still has a p300 now. Anybody have any suggestions or have similar problems?

If it isn't the coil itself, you can take a look at the ICM -- that can be the culprit.
More than likely the O2s are what is causing your misfire. I also second double checking your wires -- its common to think the wires are run correctly but they have found their way back in contact with the header primaries.
