Recently I purchased a 89 Jeep comanche 4 cylinder 2.5 l engine 5 speed manual
73k. Runs well cold but after it warms up it Boggs, stutters, chokes, and fails to respond to the gas pedal. Tops out at 40 to 50 when this happens. The idle will drop very low when I pull to a quick stop and sometimes it dies. Otherwise, the idle rests reasonably well at around 1000 rpm. If left for a few minutes to cool it will run strong again.
