Our '06 Renegade is running well except for a persistent P0303 (cyl #3 misfire) code. I replaced all six plugs and the coil on #3.
It will run just fine for a week or two, then will intermittently start to miss slightly which is really only noticeable at idle. It "seems like" it happens more often when it is damp out or raining, but can't say for sure. After it misses for awhile, it trips the check engine light.
The miss will go away on it's own for a while. I clear the code and all is well until it does it again.
I've also tried running some fuel injector cleaner through it. I'm on second tank of fuel with cleaner added.
Any ideas?
