i swapped out my 70mm t-body and went with a Edelbrock 75mm unit and egr spacer. well, on the test driver (and some today) the car will idel funny.... like a surge... and it stalled at a redlight when i pushed the clutch in.
now, usually the TPS does not have to be set.... so is this just and issue of setting the idel on the throttle body?

If you took the TPS off the old TB and put it on the new one, you have to reset it to .99v.

I wouldn't take anything for granted. Who's to say that the schmo who put that together tested to see that it was set right? lol

Check the TPS anyways...even though it could very well still be good...

Also did you get a good seal with the TB/gasket on the intake...a vaccum leak wouldn't help you out any...

Good Luck
