2020 Grand Cherokee Cylinder 1 misfire!

Question type: Maintenance & Repair
2020 Grand Cherokee Cylinder 1 misfire on acceleration. Once you stomp on
the gas the stop/start error light comes on which is followed by an engine light.
Once you turn the car off and on the stop/start light is gone but the engine
light remains. Plugs and coils were all tested. Anyone else have a similar
issue?

Had a similar problem on my old GC, the dealer couldn’t find anything so I decided to check it my self, sure enough I found a spark plug that had a vert small crack in the porcelain and I do mean small. I thought that the equipment should have picked on it but it didn’t so while is was that far I went with iridium spark plugs and that was that. Yours may still be under warranty and if so they need to keep digging. That’s the problem with todays techs if the computer says nothing is wrong that’s where they stop looking, no one is willing to do any digging.

2 year old car and you're having problems ? We used to drive a vehicle till they rusted out and then even with a bad motor would drive them to the scrap yard .
