I have a 2011 Ram 1500 4.7L SLT 4x4 with 175,266 miles on it that I need some advice on. I keep getting a random multiple misfire code, ESC (electronic stability control) light, and service 4WD light.
Here is a list of what has been done to it so far. All parts are factory replacements.

New Timing set (tensioners, guides and sprockets included)
Rebuilt Heads (Complete overhaul)
New Plugs, Coils, Wires, and Injectors
New O2, Cam and Crank, MAF & MAP sensors

I have perfect compression, fuel pressure and the timing is dead on. My mechanic and I both at a loss with this truck and need some ideas on what else it could be. I'm beginning to think that maybe my PCM is failing, but I cant be certain.

 

What brand O2 sensor? Crank sensor? Sometimes, the aftermarket fellers don't work as well as you would like.

 

All of the sensors are MOPAR Brand.

 

On member had trouble with the connectors on the injectors/coils. They simply weren't making good contact. What do your fuel trims look like?

 

Having some problems with B1. Tried the old school test of plugging the exhaust with a rag and couldn't stall the motor. Gonna hollow out my cats and delete my muffler tmw since there are no emissions where i live
