Dodge Ram Running Rough with P0201-P0208 and P0306 Fault Codes
My Dodge Ram has triggered nine diagnostic trouble codes: P0201 through P0208, as well as P0306. The P0201 to P0208 codes indicate an injector circuit open in cylinders 1 through 8, while P0306 points to a misfire in cylinder 6. I'm unfamiliar with the exact cylinder numbering on Dodge engines—could someone clarify which cylinder corresponds to number 6? Additionally, what is the most likely root cause or first step to diagnose this issue? The vehicle runs roughly and exhibits noticeable performance issues under load.
Could you specify the model year and engine type of your Dodge Ram? Are all eight injectors showing a circuit open fault? Does the vehicle run smoothly or only intermittently? Injector codes often correlate with misfires, but having only one cylinder (cylinder 6) flagged for misfire is unusual. Have you recently added any aftermarket components such as an alarm system, remote start, or modified wiring harnesses? Has any injector been unplugged or disconnected? On a conventional timing setup, the passenger side cylinders follow the order: front to back — 2, 4, 6, 8.
