3rd Gen TPS adjustment?
I haven't had a chance yet, but I've been meaning to take off the throttle body for a thorough cleaning and also clean out the IAC on my 3.4 (5vz).
I had a few questions before I start:
1)So I assume that you unbolt the 4 main bolts on the TB and the whole assembly slides out, is there any thing else besides the throttle cables that I need to disconnect first?
2)After reinstalling the TB, is there a need ro readjust the throttle position sensor (TPS)? Is it even possible on 3rd gens?
3)How much ft/lbs. should I tighten the throttle body to the intake plenum?
Thanks in advance.

Don't forget the vacuum and coolant hoses on the TB too.
There are also 2 electrical connectors (IAC and TPS).
2)After reinstalling the TB, is there a need ro readjust the throttle position sensor (TPS)? Is it even possible on 3rd gens?
No, there's no adjustment.
3)How much ft/lbs. should I tighten the throttle body to the intake plenum?
The spec is 13 ft-lbs, but just hand tight will be fine.
Thanks in advance.

Yeah, there are two hoses beneath the IAC that are sort of a pain to access. That was the hardest part in my opinion.
You'll be absolutely stoked with the results though. It made a HUGE difference after cleaning the IAC.
