Hello Scotty.I own a 1989 jeep pioneer 4.0 5speed.It operates just fine when cold.But as it warms up I'm unable to exceed 35 mph.As I exclorate when warm it seems as though it's flooded. Emense hesitation thru gears as I try to increase speed.Runs great at 35

pressure test the catalytic converters, clogged ones do that a lot. Also pressure test the fuel pump when it acts up if not that
