Car: 2005 Dodge Grand Caravan
In the past few days I started to feel the engine stumble. Yesterday the engine light came on and the error was a that cylinder 4 was a misfire (there was also a "running rich" error, but I'm guessing that was because a cylinder wasn't burning the fuel from the misfire).
So I then proceeded to change the plug and the plug wire, but I'm still having the misfire.
I'm a bit at a loss here. Could this be fuel problems? If so, would that technically constitute a "misfire", as the plug would technically still be firing? I would guess a misfire should be specific to a non-firing plug. But I'm assuming here. And also if it was a fuel delivery problem, I'd be surprised that I'm getting a rich mixture error as well.
Any additional thoughts on this? Thank you in advance.
