Tbss intake and tb swap P2135
 

I have a 2004 silverado ss and just did the tbss intake swap. I am getting the code p2135 at WOT only. And it is erratic, sometimes it throws it right when the pedal hits the floor. Sometimes it's 5-6 seconds after. I have a 3.0 xlink and tbss 87mm throttle body. My tune has been adjusted for the bigger throttle body. The throttle body works on a nnbs truck so it's fine. I was reading on here and found some info about the stock harness wiring breaking so I spent $90 on a new tac connector/harness and it still throws the code. The truck doesnt have to be running, I can throw the code with the key in the on position and the pedal to the floor if that matters. Only at wot.. Im about fed up with this thing. it is a noticeable power gain though, until it throws a code. Any suggestions?

Is it going in reduce Mode?

Yes. It used to be fun to drive. Now I'm worried ill have to pull to the side of the road and clear the code if I floor it..

I know it may be not the problem be check the battery to see its has the right cranking and voltage.i work on a truck that was throwing the reduce. Mode crap change the tb. And nothing check the battery it fix the problem never seen it again..lol

I assume your blade is sticking on something. With the key off, move the blade with your hand and see if it moves freely. If it doesnt loosen and adjust the blade until it moves freely. Report back.
