It would be a P0300 if it were the maf....not just cylinder two most likely.

I get both P0300 and P0302 now. And I did notice there's a little bit of oil leak around cylinder 2. I'm keeping my eye out on the oil level.

Would a bad injector trigger a cylinder specific code?

Injectors are probably the least likely culprit. Every time I see people sending them out to get tested they come back fine. Oil in the spark plug tubes could definitely cause issues. Very common issue, you're gonna need a new valve cover.

Can you feel a misfire? Does it happen in or out of boost?

I can't feel a misfire at all. I'm supercharged so I'm pretty much always boosted . There is no specific pattern at all. The flashing CEL just came up randomly but usually at like 30+ mph. Doesn't seem like rpm matters either.

Test pipe, right? Asking because clogged cats can cause misfire codes.

Was it retuned on a dyno when you got the new MAF?

Yea I do have test pipes with the extenders. Yes it was tuned on the dyno after installing the new MAF.

One more thing Randy. I noticed some engine oil leak somewhere around where cylinder 2. It is not a severe leak but if I drive for a while the bottom of my hood would get a little oil and so is the area around cylinder 2. I tried sitting idle and just rev but didn't notice any oil spitting out. Starting to think it's engine related.

If you have a valve cover that leaks bad enough it will pool on top of the plug and it will break the plug and/or cause a misfire...I know from experience.

Secondly, if you have a pcv problem, it will pull a ton of oil vapor (and oil) into the intake and cause a progressively worse misfire....I know from experience.

OK this is starting to make more sense. Cuz I do have a pcv problem from when Function:Tuned didn't properly put the short block in after my engine hydro locked and bent a rod. Well it's out of my mechanical knowledge and I can't really fix this issue in my garage. Back to the shop I go! (On a flat bed...)

Not completely sure, but it has to be from the frame. Or at least lower suspension parts.
