My warranty runs out in 5/24 and they’re replacing my motor due to the #7 cylinder issue.

 

No codes, no check engine light, it's a 2019, I'm checking about the warranty

 

No quick fix from a bottle. It could be the injectors, fuel pump or an electrical issue like the camshaft sensors or crankshaft sensor. What year is it? If you still have warranty get them to check it. Do you have any check engine codes or check engine light on?

 

It states that fuel should be replaced between 40K to 80K miles.

I wanted to get it done but it shows one but not sure if that one is for the Cummins diesel engine.

Mine is a 5.6 gasoline engine where is the fuel filter? And how hard is it to replace?

Please help!

That's for the Cummins. The gas engine only has a filter built into the fuel pump in the tank. If it's running fine then it's nothing to worry about

 

Is there a chemical way of cleaning the fuel system?, reason is engine on and off spits and sputters and then it dies and won't kick over until it sits for awhile like it would from a clogged fuel filter
