I just bought a 2003 Ram 1500 with a Hemi. I knew the check engine light was on when I bought it and I was told it was just an oxygen sensor. I also get my TPS light to come on and turn off all the time. I later went and checked my codes and im getting 5 check engine codes. P0420, P0522, P2122, P2112, and P2106. I did some research but im still kinda stumped on what to do. The only thing I've done so far is remove the throttle body and clean it. What do you guys think my problem is here?
