nerd some help

i dont know aboot the limp mode as i have a manual trans. is it the spacer kit? if so, the bump could be caused by the uca hitting the coil spring tower. look near the front of the bucket for a place where the arm will contact it. you should see a definate mark where it has contacted. if thats the cause, go to your local parts depot and get some energy suspension bump stops. dont recall the part#, but theyre about 3/4 inch thick. kinda domed shape an have a stud built in. youll have to drill out a hole on the uca. its there, youll see it. then fenangle the nut in there and tighten

no the noise in the front end sounds more like the sound of a bad cv joint when you turn but more so happens when I'm slowing down. My main concern now is the limp mode. I was able to have a friend bring me out a scan tool to where I was and I got 5 or 6 codes with it. The first one was a P2138. Its TPS/Accel Pedal Pos sensor D/E voltage correlation. I have read up on it and it seems that it has something to do with the tps and app working together. Has anyone come accross this problem or am I F'd and need to bring it in to the dealer? Also is the APP the same from 06 to 07?

crawl around and look really good you might have knocked a wire off or lose
