Hello , Purchased a 2015 Ram 1500 2WD November of last year, truck had a 145,000. Ran great at time of purchase, developed a lifter tick, needed the cam and lifters done. While having the engine apart I had the heads redone, new valves and springs seats etc. Below is a comprehensive list of parts Ive replaced. I always replace parts with Mopar parts.
I have replaced almost every component of the engine besides the rotational.
The last issue that we cannot resolve is a random misfire on the odd cylinder side. The condition only seems to present when I start the truck on a cold morning, the engine starts good, good fuel pressure etc, after it idles down to 1k rpm truck drives like its mis firing, as soon as I get on a main road and give it gas it misses badly and the CEL blinks. This has only happened a couple times since the temp is dropping in NY.
Funny thing is if the truck sits till the temps warm up like after work ( 3pm ) , the truck fires right up and drives completely normal. Besides this issue we have this motor running like a sewing machine, its perfectly balanced and powerful when running. When its acting up it throws codes like PCM P0 307 cylinder misfire, last time it was cylinder 5 and once it was cylinder 3. Which leads me to that bank ( odd bank ) but cannot figure out what is causing this.
Sorry for such a long rant , just trying to be conclusive as this issue has been hard to figure out
