Hello all. Been a member for a few months. Mostly lurk in the detailing section. Some very nice trucks here. I'm having an issue with my 11 Ram 5.7(99,900 miles). At 3,000rpm, under a load, I get P0305 fault. The engine misses bad, almost to the point of non-drivable. I have put new plugs in, not knowing condition of the old ones. I have also switched coils from #3 to #5 cylinder. I'm looking for some advice on where to go next. I'm having trouble understanding why it runs fine until almost exactly 3,000 rpm? Also, gas mileage has dropped significantly. Any help would be greatly appreciated.
Thanks

Hi [email protected],

If you end up taking your vehicle to a Ram dealership I'd be happy to follow up with them for you! Just send a PM to our page with your VIN and contact information if that's the case.

Next thing to try would be swapping injectors.

Thanks for the replys. Found out I have a few days left on my power train warranty, so I took it to the dealer. I believe that I have the stuck lifter, wiped cam issue.
