2012 2500.... literally - same - exact - experienceWell, here we go. I just dropped my 2009 banana Ram off at the dealership. They are looking into my random P0305 code and misfire issue. I experienced an engine vibration/lack of acceleration and CEL when I was getting on the interstate a couple of weeks ago. Stepped on the gas and the banana Ram fell right on its face where its always been a strong performer. Since that day I've been experiencing the typical issues many have discussed here when the cam/lifters start to fail. Stumbling under acceleration, a bit of a rough idle and random CEL. At the time I just assumed my baby was ready for a new set of plugs. I'm just under 129K currently and the last time they were changed was at 75K. I had a new set of plugs in the garage and ready to go since I had planned on changing them at 125K...
I changed plugs last week (checked the gaps and torqued them all properly). The old plugs actually looked really good with no signs or issues with any cylinder in particular. Since the old plugs looked good I decided to swap coils around just in case a coil was the problem. I greased up the coil boots with a good dielectric, checked coil wiring and connectors and put it all back together.
The banana Ram fired right up and idled smooth. I took her around the block an she drove well and felt as good as ever. Looked like the new plugs did the trick... right?
Wrong...the next morning I went to the Post Office across town and while driving I stepped into the throttle a bit and wham... engine stumbles, misfire (P0305) and CEL comes on again... I feather the throttle and it recovers and goes back to normal. Crazy thing is that it will drive nice and smooth and even cruise at highway speeds as long as you don't step on the gas too much.
I would love to hear that its only a fuel injector but I'm not confident that's going to be the problem.
Waiting on what the dealer has to say now...
