Alright, so after running an intake leak test and finding out that both throttle body gaskets AND shaft seals were leaking, I decided to replace them all. Everything went pretty smoothly, and it is finished... kinda. We(my father and I) ran another leak test to make sure everything was good. We found a HUGE leak near the bottom of the TPS sensor. So we took the black plastic part of the sensor off to see what was going on. Turns out, there are two large spaces that air was flowing freely out of. Now, this wasn't leaking before we replaced all the gaskets, so obviously we messed something up.

So, I think I MIGHT know what is missing. This little piece right here that my dad decided to rip off with a pair of pliers because "it was rusted and didn't serve a purpose", all while I was inside getting a drink. It looks as though it might be what is supposed to go in the two holes on the TB at the TPS. He says he doesn't remember where he tore it off at, but he's pretty sure it was at the TPS.

Here you can see the two holes on the TPS (black plastic thing was taken off) where air was leaking during the test...

Sorry about that. I tried using Yahoo to upload images and it didn't let me use the URL to put the pics elsewhere on the internet. All better :)
 
I'm thinking something, but not sure if it's correct. Is air even SUPPOSED to get to that area? I was thinking that the shaft seals we replaced were supposed to prevent air from leaking out, but it seems they aren't doing their job? We replaced the seals with brand new o-rings, so I don't see that being the problem. :confused: :(
