Well, I would not assume it to be the TPS, but I wouldn't count out the MAP sensor or wiring harness itself either... it's been a long while, but don't remember the MAP voltage being reported via OBDII. That sensor can make a word of difference is only reason why I keep going back to it. If memory serves, your computer needs to see no more than 4.7v or it'll throw a hissy fit (and go too high and it'll throw a code), and that sensor needs to be 'perfect' through the entire range. There's a lot of heat behind the head which is where that wire is run.
Not sure the symptoms of a CAM/Crank position sensors, don't think I've ever needed to replace one, but something to check. Regardless, there's not 'that many' sensors to check.
