throttle cable adjustment

**DOCJHH45** · 11-04-2008, 12:20 PM

Just noticed the cable is not pulling WOT when the gas is floored... anyway to adjust this?

Thanks

thats what i was wondering but i think the only way to fix it is the bump stop mod

I think he mean that its not even going to hit the factory bumpstop.. ive heard of this issue as well...

correct, there isn't enough tension on the cable to make it hit the bump stop.

I had this issue when I data logged and only was opening 84% with the gas pedal, but could manually open to 100%. I followed the cable back from the T.B. and found these in-line pinch style couplers toward the firewall before the cable turns over toward the battery. My cable was loose and slipping in the coupler. I moved the cable and pinched the coupler tight with my fingers and it fixed my problem. Give it a look, mine is a 2000 SS A4.

I found this as well on both of my 4th gens. First thing I did was to make sure the floor mat isn't under the pedal. You can also pull the carpet away and trim some of the insulation from underneath.

I was scanning mine, and even after the bump stop mod I couldn't reach full voltage on the throttle position sensor.

I found that the gas pedal was hitting the floor long before this happened. I ended up removing the pedal and bending the rod slightly to gain that added bit of pedal travel I needed.
Now it just hits a bump stop under the dash on the other end of the pedal rod,,,lol. But I managed to finally reach the maximum TPS voltage that is considered acceptable.
