Hello everyone

I have a 2008 ranger 2.3 that has a misfire. I notice that it happens more often that other Times. Every time I stay at a constant speed it let me speed up and I would have to let go of the gas pedal until it down shifts to another gear. I’ve replaced air filter, fuel filter, TPS, IAC valve, Etc sensor, coil pack, spark plugs, wire set, cleaned the throttle body, cleaned the map sensor, replaced both catalytic converters, replaced the muffler, replaced the pcm, and replaced the pcv valve. I’m struggling to find the issues ☹. Can anyone thow some insight in my dilemma?

Do you have any codes for us to work with? It might help us help you if there are any.

My credo
My world is filled with stuff that needs to be fixed
Every time I stay at a constant speed it let me speed up and I would have to let go of the gas pedal until it down shifts to another gear
Can you rephrase this? I didn't understand it.

There are no codes coming up,And what I meant to say is when I’m traveling at a constant speed and I try to go faster it Will start to misfire and won’t let me accelerate. I have to wait till it downshifts and then I can continue Accelerating. Also if I’m at a stop it will jerk and die out sometimes
