Throttle Cable Adjustment

[Blackgri]

I recently performed a TB adaptation on my ‘’97 with Vagcom. The reason I did it was the battery was out of the van for a while and I wanted to reset the TCM after a fluid change.

The issue I am having is the TCM is only seeing the throttle at 75% even though the throttle is wide open. This in turn is not allowing the kick down to work properly. I am able to physically hold the TB open to get the TCM value in Vagcom to 99.5%.

My question(s) to any takers is there a throttle cable adjustment or is a replacement in order? Am I missing something else?

With the pedal all the way to the floor, the TCM reads 75%. If I force the throttle body all the way open with my hand, it reads 99.5%.

You can adjust the throttle cable where it attaches to the throttle-body. The end of the throttle cable housing has a ribbed section ~2" long; a clip secures the cable housing where it passes through a grommet at the throttle-body. Relocate that clip further down the ribbed section of the housing to "tighten" the cable, but don't apply any pre-load onto the throttle-plate itself (i.e. make sure it still closes all the way following the adjustment).

Another area to inspect is where the throttle cable attaches to the pedal assembly underneath the dash. There is a bushing in the linkage where the cable hooks through; the cable's hook wears through that bushing over time, creating another 1/4" of slack.

The clips holding the throttle cable to the bracket are MIA. I’m guessing the mechanic that replaced the chains a couple weeks ago misplaced them when he extracted the engine.

Anywho, I safety wired the cable in place until I can source some clips or bite the bulletin and replace the cable. Thanks for the help!
