    See, I don't mind throwing parts at it. It's a hell of a lot cheaper than throwing parts at the plane and I like a good challenge.

    Ok, changed the fuel filter. Apparently this is a Flex Fuel vehicle. Learned something new.... While the P0300 code hasn't shown up yet, I did get a flashing CEL while idling. Idle still feels lumpy. I can still feel a bit of a miss. KOEO - 45 even.

    Should I post the live data here?

    Hey guys, I've been searching for this for a while... like 2 weeks. SO I figured I would make a post to see if you guys could help me. 2005 Suburban - 5.3L - 200k I picked this thing up for a song... literally. Exterior is awesome, interior is awesome. Had a P0300 code and the guy didn't...
