Subject:Was: CO..... Setting. Now: Engine Bucking Issue Solved?

Hi all.

The clip that holds the accelerator cable to bracket on transmission, was
missing. I made one, it seems to help.

Would a missing clip allow the accelerator cable to move back and forth in
the bracket and negatively affect the throttle valve switch operation?

New clip installed, it doesn't seem to buck when decelerating. It surges
sometimes when accelerating from low RPM, say in 2nd gear, but I'm testing
the van using abnormal driving techniques.

Hope this  $0.10 part solves the problem!

Neil.

Extra reading:

I wondered all along if the accelerator cable was being pushed/pulled due
to worn engine or transmission mounts thus causing the throttle valve
switch to open when decelerating.

This Vanagon was sold to me as a relatively low mileage vehicle (~ 85K
miles) so I assumed the engine or transmission had never been removed. I
doubt the accelerator cable has been replaced as the rubber boot is torn.
Can't see another reason for that cable clip to be missing.

On my '81, after swapping in the Jetta engine I had a similar surge issue;
surging at low speeds (parking lot speed) I had mounted the accelerator
cable to the firewall. Mounting it to the drivetrain cured that issue. I
had similar thoughts towards the minor surging or bucking on my '88 but had
assumed everything was OEM, stock, not molested.
