Hey guys I’m not sure how to word my question other than after I drive my 98 TJ for about 20 minutes on the highway if I stop somewhere or at a light or drive thru my RPM’s go way down to the point of stalling and when I push on the gas it doesn’t rev. It only happens when I drive it a lot that day. I haven’t been able to find anything online due to the wording problem. I’m just confused. I saw maybe a fuel filter but that doesn't seem like the issue cause it’s only occasionally happening.
