I thought IAC but then the idle would be f'ed up all the time, it comes and goes. So i'm not going to take apart and clean the IAC. But the fuel filter and the fuel rail pressure sensor is a possibility. I'm going to run the codes at my friends shop when I get the chance. Until then it's all guesses.

Clean the MAF.

Good catch - we all missed that. Also if you have an aftermarket intake, might want to put a recharge kit on it too.

I'm going to put in my new plugs and clean the MAF tonight so i'll let you guys know tomorrow. Thanks for all the help!

New plugs and the MAF cleaned up along with the throttle body, intake, and such. Had a smooth ride home from my buddies house, but didn't drive her enough to see if she still stumbled. Anyway, now when she idles she'll idle really high, still runs rich, and after pulling the plugs I found out my right bank is running insanely rich! All the plugs on the right hand side of my engine are BLACK! Not from oil, just from running rich. What could be the cause of this now? the left bank is perfectly healthy.

Lost a cylinder you did

Possibly the coil packs? If it's not the plugs, it could be the souce of the spark, though the each coil pack does 2 plugs on both sides, so that wouldn't explain ALL of the right plugs being bad and none of the left. I agree that it probably has nothing to do with the IAC since that wouldn't affect it at all up to speed, unless your idle issue were differen't which it probably isn't, however, you can still clean it. It's literally a 10 minute job, from opening the hood to closing it. Just unhook one hose, unscrew two bolts, careful with the gasket, take it off and clean it out with some carb cleaner or similar, then slap it back on.

I actually cleaned the IAC, it was pretty spotless when I took it off and even more so when I put it back on. I'm thinking it might be an o2 sensor. Is that possible?
