Bought Wrangler with 51000 on it, with AC on @ highway speeds, CEL light will come on, it throws a P2074 code after about a half hour on the road. Loses power and is hard to shift. Turn off ignition a couple of times and it seem to run better, then the next day into work with AC off @ highway speeds all gauges will zero, engine will stall for a moment then come back, CEL will go out and it will run great! Happens on almost a daily basis if I run the AC. Looked up the code and checked for vacuum leak, replaced MAP sensor, replaced TPS, still doing it.
