I just changed out the head gaskets in my 2001 4.7 Durango (had coolant on the plugs :smiledown. After everything was put back together, the vehicle is running really rough and hard to start. It is throwing injector codes, coil codes, and a random TPS code (P0202, P0205, P0207, P0352). I have changed out the injector on cylinder 5, the coil on cylinder 2, the TPS sensor, IAC valve, and spark plugs. There is also a really loud sucking noise coming from the throttle body and when you plug the vacuum line from the TB in the brake booster, it starts to stall. I'm guessing vacuum leak, but what about timing or PCM? Need help asap!
