Throttle Sticky

Hey guys. My throttle every now and then will get stuck closed. It likes to do it after deaccelerating and i'll have to break it loose a couple times and then it'll be fine. I found some threads with info about possible solutions but the links to pictures are expired. My question is does this sound like a problem that adjusting the set screw on the TB will fix and if so does anyone have a picture of the screw location? My car doesn't have a stock TB either. I believe its a Steeda but I'm not positive. Thanks in advance!

Make sure you did NOT overtighten the hose clamp on the throttle body.
Try leaving it just more than finger tight and see if that stops the sticky throttle.

Adjusting the throttle screw is a no-no once it's set for the idle, the IAC expects it to be in a certain spot. And, if you go the wrong way you just made your problem worse. Resetting the screw can get you hanging idle issues when the IAC suddenly repositions based on the screw adjustment. It may be sticking there, the normal position is what keeps the shaft clean, when it moves off that the shaft can stick from deposits.

So did a good clean on the TB. It had a bit of gunk but nothing that should stick the throttle. See if it works. I also left the hose clamp a little looser. Can anyone identify this TB?

So it's been a couple months and while the throttle doesn't stick as often it's still doing it. Can anyone think of anything other than the TB that could cause the pedal to stick?

Check the cable to ensure it moves freely, as well as the pedal itself.

I've checked and rechecked. Everything moves silky smooth until it doesn't. And then I break past that point where it sticks and it's perfect again. I'll recheck the pedal because that had to be where the problem is.

start engine , unhook the idle air control valve , engine should die , restart engine and set idle screw to about 750 rpm , reconnect the idle air control valve and see if that helps

If your lucky you will have to screw the screw in a little to achieve the 750 , whats happening is the springs on the after market TB are very strong and the throttle plates are very sharp and over time the plates start to ware into the TB housing and binding it up at closed throttle

If the above doesnt work for you you can take the TB off and there is another thing you can to to the plate that helps

I set the idle to 950 in a tune and with the idle higher your screw can go in further taking the throttle plate further away from where it is binding , but you have to buy a tune to do that

I'll try that when I get off work tonight. Hey Tom, are you running any specials on NA tunes for my SVT?
