Figure out if it's the TB sticking or the accelerator cable. Disconnect the cable and test the TB opening and closing smoothly. These cables have a bellows that fails and gunk can get into the tube. http://www.gowesty.com/product-details.php?v=&id=3524

Check your pedal too.

Hi all,

Have a couple hundred miles on the this unit now. Initial feedback was great until this morning.

http://www.gowesty.com/product-details.php?id=24718

I experienced slow or no return on the TB upon letting off the gas on the freeway. Go to shift from 3rd to 4th and the RPMs remained steady in the 3-3.5k range through the shift. If I left the van in gear and slowed down via braking to 2K RPM or thereabouts, the idle would return to normal upon depressing the clutch. Let off the accelerator while cruising at 3k RPM and I could tell the van was not decelerating as it should be. Depress the clutch pedal and RPMs did not drop to idle levels. TB was not closing.

Thoughts? I'm wondering if the original tension spring isn't up to the task and needs to be bent/shortened some to increase return force on the TB. Never had this issue before the new TB.

87 GL w/ Rocky Jennings 2.2L motor.

thanks, Andrew
