Hi,
I have a 2010 Ram 1500 with a 5.7L Hemi.
Recently my truck started to flash an engine light under medium (2k-3.5k rpm) acceleration.
The code reader showed an error P0305.
Also hesitant at times during throttle & rpm gauge slight variations (200rpm surge) during normal driving conditions, also it would shake very little once throttle released again and cylinder picked up. Defiantly not good on the engine!
-So I installed new identical part # spark plugs, no difference, still code P0305. Same symptoms.
-Swapped out coil pack with another cylinder, still P0305 flashing during acceleration.
-Removed #5 FUEL INJECTOR, inspected and even swapped out with a different cylinder and still throws a 0305 code, only flashing, no steady engine light.
-I inspected MAP sensor, cleaned the camshaft sensor, and air temperature intake sensor, no change.
Engine has noticeable higher pitch tick at idle aswell which sounds like it's coming from #5 cylinder.
Truck is parked for now, not sure what next? I don't have the tools for a compression test sadly, I will add a picture of spark plugs I replaced.
