It's nagging the hell out of me because I've seen this before, but I can't remember what it was. Sorry Paul, I don't think it's the TPS. If it was, it would be drivable with or without the MAF unplugged.
Im goin to check for vacuum leaks again. I feel like i have a vacuum hose crossed or something. I DO HEAR HISSING when i start up my car for a little while till the engine calms down. Do you happen to have pictures of vacuum lines/hoses? That would help me eliminate an easy fix. Also my car backfires alot when shifting.
