It's weird when the car is not running it pushes easy. When it's running I have to put a little pressure on the pedal to unstick like coming off a red light but after that it's fine. It's only when you push it after you let off it. What could this be?

It sounds like the throttle body blade it getting caught when it comes all the way shut. You could adjust the throttle stop so it doesn't come back so far.

How do I do this? I did the bump stop mod. It's only sticking when the car is running.

There is an adjuster nut on the TB, it ran be moved out a little. You may have to remove the TB to get to it.

I circled it in this pic. I hope this helps!

Had this on a Blazer that I owned. Solution was to have the throttle body cleaned out. This solved the blade from sticking.

That is always a good possibility, the PCV may be letting some oil get down in the TB.

Umm maybe im missunderstanding, but wouldn't adjusting the idle screw make it idle higher?

I just tried cleaning the TB but it's still sticking and the idle screw can't go any higher. From the looks of it I think the bottom of the blade could be ground a tad I mean a hair what you think. And can I just sand the bottom a bit?

I really wouldn't do that if i were you...by doing that you will increase the gap between the butterfly and the TB opening in turn alowing more air through and creating a high idle problem. try taking off the TB and adjusting the butterfly by losening the screws that hold it on. Good Luck!

i had the same problem when i Ported my tb and i also did the blade mod, where i grinded the ends to make it flow smother! if its really bad, you have to take the tb out and grind the ends all the way around the tb blade evenly! and then you have to adjust the main idle screw that is outside of the tb. if your idle is a bit high (lik 1000 rpm) then you have to keep making adjustments and if you get pretty close then thats ok, in a few days the computer will automatically adjust the iac solinoid to bring it to its normal rpm

Did that nothing! I'm going to knife edge it.

I recommend using blue loctite on the throttle blade screws for this.

Loosen the screws to that the blade can "adjust" itself to be centered within the throttle body. Don't tighten it too much, just enough that it's set into blade, but if you push on the blade with some good pressure with your finger tip it'll move.

When I ported mine, I did the half throttle blade cut and found if I tightened it down too much, the blade would stick. The blue loctite has held for the past 2 years so I'm pretty sure it's not gonna fall out by now, but the blade is still loose enough to be shifted.
