I have an 05 Ram 1500 with the 4.7L. I hydro locked it, broke a rod, so I got a re-manufactured 4.7L and swapped it in. Fired right up no problem at all. Seemed to be running fine, no lights on the dash, so I went to go for a test drive. Pulled up to a stop sign, went to put the window up so I could here the engine better and the second I hit the button for the window it started chugging. It's missing like a mother but not throwing any codes. Anyone got any ideas?
