Hello,

My 1999 A4 V6 is only showing 76% at WOT. The reading is from an OBDII monitor while I am pushing on the throttle with my foot.

This may actually be correct but I am looking for some opinions.

Thanks,
Chris

 

chech that the throtle cable is working and does not have a lot of play.

I had similar, but I simply tighted up the cable and got extra like 15% go.

check it out.

Just out of curiouasity, simply pull the throtle body by hand and check the %. That way no guesing.

 

The throttle cable is fine... I took apart the underdash and verified that the pedal was pulling on the cable the correct ammount. I got an extra 1% which is nothing worth metioning.

Are there any other adjustments that anyone may suggest. I really don't want to dig to get to the TPS unecessarily.
