Well, wednesday afternoon I think that I found out what the problem really is. I took the throttle body off the upper intake and worked on it a bit. At first I noticed that when I worked the linkage, it was grinding and difficult to operate. So I took the IAC and the TPS off and it freed up some. So I cleaned it up with some carb cleaner and lubed every pivot point with WD-40, and it freed up some more. BUT, I noticed that the arm that is attached to the throttle plate has a slight bend to it on the outside of the body. It comes out of the housing and starts to put everything in a bind just after part throttle. I cleaned the TPS with some electical contact cleaner and stuck the dude back on. Again, after I reassembled everything, it started the hanging up again. But this time I backed the throttle screw off just a bit, it still hangs up just not AS BAD.
I have a 3.8L SC throttle body that I am already considering putting on in the stock ones place. I just have to drill out the holes, and open up the upper intake to accept the "new" throttle body.
Is there anything that I need to know before I make this mod??? Other than the fact that I have to bump up the fuel pressure just a bit so it does not lean out up top. Can I force the issure of using a TC TPS on the SC throttle body??? It looks like it might work for a while until I can get the proper one.
Oh, and I pulled the codes and got just the usual ones, EGR, BOO, EGO Rich (I am running 45 PSI on the fuel pressure to avoid detonation on 91 octane).
