P0068 2006 Dodge ram 1500 4.7
This is a 2006 dodge ram 1500 4.7l I was driving for 2hours+ and needed to fill up. Fueled up and noticed when I came to a stop my idle was very rough. After driving for another 20~mins I got a check engine light. Had the truck towed to my house and checked the codes. I had a p0068,p0113,p0172,p0175. I replaced the MAP sensor and IAT sensor. This didn’t fix the issue. I had disconnected the battery so all codes would reset. When I rescanned for codes I had a p0068,p0300. I went on to replaced the TPS, (even though I tested and seemed to be working) IAC valve, cleaned throttle body, replaced all spark plugs, and replaced PCV valve. Still had same issue. Noticed truck hesitated starting basically a hard start and when driving it will stall when stopping, also has hesitation when pressing gas from idle. When going it 20+ mph is has no issue. Did a smoke test and found leak on exhaust manifold but nothing on intake side. I thought it might be bad fuel so I had drained gas tank and refilled with fresh gas. This didn’t change anything. I know fuel pump is working. I am at a lost. The only thing I can think is the PCM is sending false info causing it this rough idle and all other issues. Rescanned after replacing all of this and the only code I have now is a p0068.
