Cylinder Misfire Normal?

[Ramtrucksrock95]

Any update to this issue/normal operation? Mines a 2019 and I have the same thing. I however, notice less misfires when I fuel up at gas stations that are not Costco.

Oddly enough I have a 2019 Ram 1500 5.7 with 57k miles. #8 fuel injector was replaced due to it causing a misfire. Dealership said there are misfires on all other cylinders but not enough to cause another CEL and suggested to add a fuel system cleaner in the tank. I normally add seafoam every so often. I put Costco gas almost exclusively in this truck. Is it the Costco gas causing this? A friend who is a service advisor at Lexus suggested me to not use Costco gas because his customers experience issues as well. Truck is still at shop but now debating if I should have all injectors replaced or try my luck with Berryman b12.

This screenshot was after a 10-15 minute drive. I’ve been noticing some odd throttle issues from time to time as well as a rough idle. This past weekend the check engine light game on and I grabbed this screenshot. I tried swapping the ignition coil from cyl3, but no change. I took it in and two of the injectors were replaced. It’s running so much better now. I am going to avoid that cheap gas for now.

Yeah. Is there another app that also has access to viewing the live data for individual cylinder misfire counts?

I’d really like to see if anyone else with the JScan OBD2 scanner app sees the same on their end.. I don’t see any indication of a noticeable misfire but since I had my engine replaced I just want to be certain it’s the app or “false positives” rather than a true issue.

My 2023 hemi does the same thing.. sometimes the counts are super low, sometimes I’ve had a cylinder as his a 15 misfire counts. Never have a CEL or anything Dealer swears nothing is wrong. I’m wondering if the PCM is adjusting to certain driving conditions and it picks up as a misfire, I don’t know but also, the engine running at idle 500 or so RPM. The misfire counts are super low, considering 500 rpm’s or so like a .004-.03 percentage I don’t know what the threshold is normal and what isn’t…

I’ve had some too. I just quit looking at it
