Sticky Pedal/TB, only when runing

[basballny2]

I think your idle screw is set too high, back it up a bit and see if it doesn't solve your problem.

didnt solve my problem, took the screw all the way down to the point where it was making the butterfly stick in the TB and its still idling at 1300 RPM.....could it be i need a tune that bad? ive done headers/ORY/exhaust/UD pulley/pp TB all without a tune. Do you think i just need a tune?

Could be a vacuum line off, the breather system leaking, or the hole in the blade is to big. A tune would be nice also !

where can i check if the breather system is leaking? i switched my butterfly to the stock one and still having the same problem.

On my 98, there was an elbow on the drivers side valve cover that was known to crack open. All that stuff has been deleted off mine.
Maybe, the new TB is leaking air around the blade / plate ??? Over ported ?

if the TB sticks when the screw is all the way out, then the TB blade isn't centered in the TB. That what happened to me. If you take the TB off and hold it up to a light you might see light coming through on one side but not the other.

My issue has been resolved. The idle screw was too low, creating a vacuum behind the plate.

im guna try putting my stock TB back on 2marro and seeing what happens

I was thinkin about this last night...if this doesn't work, unscrew the sensors and make sure they're seated properlly.

FWIW, you said that when you backed off the screw all the way you had the same vacuum issue I had. Do that, then turn it in literally 1 screw.

Or, you just need a tune. lol
