If you have a 2000 Jeep Cherokee Sport and the engine bogs down at stops or slow speeds when electric cooling fan engages stops when fan kicks off?

Answer 1

Try checking ur pickup coil... Had that problem with 89 but turned out it was ignition control module but in a 2000 if its v6 then you most likely have a pickup coil.

Either that or try checking your fuel filter, may sound benine but if the filter gets clogged it can cause those problems at loxw speeds, but when you are going at about highway speeds and no stopping, it is allowing the fuel feed. but at low sppeds pressure is decreased therefore the feed to the injector is also decreased.

I forgot to add, the RPMs seem fine, but engine "sounds" like it suddenly got rough, there's a minor vibration, and it only happens at slow (5-15mph), speeds or stops. Today it only did it when electric cooling fan kicked on and stopped when the fan shut off. The first time it did this was at a complete stop after setting for an hour, and in park. Sometimes shutting the engine off, and cranking again fixes it, but only for a while or until next stop.
