Flashing CEL misfire

[Amazing93]

I started my truck and noticed the idle felt rough. I drove it about a mile and each time I accelerated I got a flashing engine light. When I took my foot off the gas it went away. It was obviously a misfire. I shut the truck off started it again and now its fine. Anyone else run into this issue? Only 8k miles on my truck. 5.7 non etorque. I only use top tier gas usually from Costco and I have always used 89 octane or higher. So fuel quality should not be an issue.

Just read the code with my code reader. Nothing active but fault P0302 is pending. Misfire in cylinder 2.

I apologize for the trouble, @Amazing93. If this is something you decide to address with your Ram dealer, we would be more than willing to escalate a case on your behalf to a specialist for further support through that process. Please do not hesitate to follow up via private message with any additional questions.

I would definitely take it in even with a pending code to have it on file and checked out. No vehicle with 8k miles should have a misfire.

Could be corrosion on the connector to the coil pack, or the coil pack itself. It's nice that those are easily accessible on the Hemi as opposed to the Pentastar where you have to remove the intake to get to half of them.

I'd swap two coils around to see if the fault follows the coil or stays with cylinder 2. It's not an MDS cylinder so you don't need to worry about a collapsible lifter problem
