Possible TPS failure

I'm still trying to find why my car is getting this loped idle, random sputter type deal. I decided since it's warm out I'll check the TPS, since I have cleaned the TB multiple times, and there have been at least a handful who had their TPS crap out after messing with the TB.

Anyway, what kind of volts am I looking for while testing? I've searched, and nothing really. I read 0.5 to 5.0, but that seems like a big gap.

The only vacuum lines that would strike my attention are the ones off of the intake manifold or the brake booster? I don't see very many.

you should know where the seals are at if you installed the 2.4 intake manifold. If not oh well, you are kinda being a nanner and im trying to solve this issue. Id say take the manifold back off and make sure its all clean with a good seal on every o-ring. Just to make sure.

Yes, I know about the seals/vacuum lines around the intake manifold, but there are definitely no vacuum leaks around there, I've replaced the seals when I first installed it.

Would it really hurt to uninstall and re-install? besides take up maybe a hour of your time tops.

See.. The thing is, I'm pretty sure it idled like dick before the manifold, too.

I'd say I'm like 75% sure.

Im just saying that it can still be a problem. Why are you being a dick to me when im trying to help you with a problem? Maybe thats why nobody responds to your threads. Just sayin.

Dude, I'm not being a dick.. I'm just saying if the shitty idle started before the manifold swap, why would I go ripping a manifold off?

I completely understand you're trying to help, and I am open to any and all suggestions.
