Stumble when warm.
I am getting a hesitation when I push on the gas with a warm engine. No hard code yet?
anyone been down this path?
thanks,
I have checked plugs 18k on them. Used dielectric on plug ends

If you have a scan tool do you have any current or pending DTC’d ??...do you mean current DTC’s when you say “hard codes” ??...this can be a number of things but if you have a scan tool and can interpret data PIDS that may give you some direction...di electric grease is actually an insulator so you have to be careful when you use it on plugs and plug wires...your concern may be TPS, MAF sensor, fuel pressure and a few more I may have missed.

Most likely a dirty throttle body. I use a lint free rag with rubbing alcohol to wipe the throttle body (including as far as I can reach into it, which is typically all the way to the end) and throttle blade (front side, back side, and the thin edge) down until it's clean. You could also spray your MAF down with MAF cleaner. I just finished doing this on the wife's 2014 Charger (83k miles) as I was noticing a slight hesitation at any throttle tip-in. The hesitation is now gone.
