1989pioneer

fresh 94 octane

sorry about that it is a 4.0 and i just put a muffler on it and it did help so I'm gonna try and get a small cat on it cuz i am gonna put a stack through the bed near the cab.

also my dad who also has comanche said it might have something to do with not having an exhaust.

i looked under cab and noticed entire driver side floor rotted out gonna cut and weld this week end.

I'm new to the form and i have an issue i would like to hear a differnt point of view i have a 1989 jeep comanche pioneer just got it on the road been working on it for a while now and never had an issue while accelerating i get a spudder not quite sure what it is when it is idling it is fine any thoughts.
