This started a couple of weeks ago. When the truck starts the idle fluctuates. When I push the throttle down it will only go to about 1500 rpm. I suspected it was the tps. I got what I thought was the right tps. Had everything removed and my neighbor came over. I realized it was internal to the throttle boy. I put it together real quick to show him what was wrong. It started up and ran fine for 4 days. The only thing I had done was move the butterfly in the throttle body. So it happened a couple more times and moving the butterfly fixed it til the other day. When it gave out I thought for sure it was the throttle body. Replaced it and same problem. This time it gave me codes. They are p0642 p0335 and p2122. Any ideas?
