Anyone have a sticky gas pedal?Here's the sich...a couple conditions where I've noticed a 'sticky pedal' afterwards1) prolonged non-changing throttle position (long highway stretch)2) hard run up through a gear (I'm talkin' spin 'er up to 8 grand..GT owners only please)3) after a prolonged deceleration in a gear...after these conditions, when I go to pick up the throttle again, smoothly I might add, and I push a bit, then a bit more, then 'boing' ok there it goes.I have 70k on the car. I have removed the air intake hose to the throttle body and cleaned up the butterfly (even though it did not appear to have any hesitation or hard spots on it). I was tracing the throttle cable back and it goes to the cruise control module...don't know what's happenin' in there.Any ideas on lubing the cable...looks like a mess waiting to happen.This condition is not a safety issue, its a driveability issue...its tough to be smooth when the pedal doesn't move when you want it to. The throttle itself does not stick, the butterfly always closes and she drops back to idle, but when you go to pick it up again, there's this stickyness until something breaks free. I usually just poke the pedal real quick like, then I can drive nice and smooth for a while.Other occurances? ideas?

The same thing happens (kinda) in my wife's Nissan Sentra, I am curious to hear of possible solutions as well.

could it be some sort of vaccum pressure?

this happend on my 2000 SUV. They said it was a sticky (weak) spring in the TB.

I don't have a fix, specifically for the vibes. But my 87Mustang GT's TB liked to stick at WOT... yeah, that was a white nuckle ride in 3rd. It would also require more effort to get it off of idle - like you're having.Anyway, I did everything I could thing of. Even disassembling the TB and honing it to get the slight lip out of the aluminum that would catch the butterfly created by rarely going WOT and just wearing away the most used area. I even adjusted the set screw just a hair off idle, which didn't help my MPG. But it kept it from closing all the way.The spring was strong and the cables were good - it was just catching on an little lip in the aluminum that had worn away. It seems to go away when I bypassed the coolant hose - but then I had problems in the winter.So I ended up just replacing the TB assembly. Feel along the inside of the TB channel - remember it's going to expand when it heats up. I went with a 75mm upgrade, so it had a silver lining.
