Sticky Pedal/TB, only when runing

**Vertiviper** · 05-30-2010, 10:26 AM

I just swapped my TB for a PP one. When the car is running the pedal/tb is very sticky when it first opens. When the car is off it feels fine.

Anyone have any ideas?

Thanks

I had to remove my TB, loosen the idle stop screw all the way out, and then loosen the 2 screws that hold the TB blade to the shaft. Open and close the TB a few times. That'll recenter the blade. Tighten up the 2 screws that hold the blade to the shaft and recheck to make sure TB doesn't stick. Then readjust the idle stop screw back to where it was and reinstall the TB.

I tried that, no dice unfortunately.

The fact that this only happens when the car is runing I think leads me to believe that either the hole needs to be a little bigger (i only have bolt ons), or when the blade is closed, the seal is too tight. Comparing my stock vs my PP TB, the PP TB has a much tighter seal around the edges.

I even tried using the old blade on the PP TB..no luck.

Turn in the idle screw some. Don't let the blade close completely, or it will stick.

Correct me if I am wrong, but aren't the throttle blades on a slight slant? I replaced a water pump on an 04 Suburban and I looked at the throttlebody while the intake elbow was off and noticed it looked like it was slanted a lil bit.

mine used to stick because of vaccum when the engine was running, i adjusted the blade a little and the idle screw and it solved my problem.

Where is the idle screw?

You have to take the TB out in most cases. It's what stops the TB from spinning backwards. Like the opposite of the bumpstop. i know someone can word it better.

lol...i figured out what you were talking about, I just didnt know the correct word for it. It's, when the blade is closed, the little nub that the arm rests on:

Funny thing, my cousins idle's too high, mine is actually a little low..

Thats it, it's a pain getting to it on the car

**basballny2** · 05-30-2010, 06:01 PM

see, now mine is idling high, and when im driving and put the cluth in it revs up to 3k rpm until i shift into a new gear and does the same if im driving and put the car in neutral......think its my idle screw also?

Does the pedal stick at all? It could be. You could check the voltage at the TPS at idle, its supposed to be within a certain range, not sire what it is exactly at the moment. If it's off it could give you problems

Yea..I need like an L shaped Torx...or use a really small fine toothed plier..

I believe this is another excuse to go buy some new specialty tools. FTMFW!

Cuz,...this is def it.

pedal is not sticking, although this would make sense because the car was constantly surging even when i wasnt gasing it..... i didnt touch the gas once for 2 exits and gained 10 mph.....its weird

Does it idle high?

We've clearly created a perpetual motion machine!!!

at first with the butterfly it came with it was idling at around 3k RPMS, looked and saw the butterfly had a larger hole and switched the butterfly to the stock one with the smaller hole but its still idling around 12-1500

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

I had one with a hole to large & got a rubber wire grommet to stick in the hole. If you try this, make sure it fits tight, so it doesn't suck into the motor ! LOL !!!
