    Could be not getting enough fuel at idle. Maybe motor mounts. Maybe electrical. Can you give everyone more info?

    a clogged fuel filter? A fuel filter not installed right, causing it to suck air?

    Its got a davco glass bowl fuel filter right? Is the fuel all the way up to the top of the bowl? That means clogging filter.

    Have check engine light ? I think u can read codes with 6 on/off key cycles iirc

    Just clarify, I don’t wish to misleading. The glove setup I mentioned was more for working on the truck fixing stuff in the cold. So the fingers can move, still be flexible and be halfway warm.

    these in the picture are the ones I use year round except in the winter. Usually get about 2-3 months out then give or take. 0FCC4828-5E5A-4CEA-924E-6A20FA694F9E.png

    These are the extra gloves I picked up for all purpose this winter. Fueling and flatbed etc. E546DBFD-FE5F-4DE0-BC53-8B1C3AE1EBFF.png

    The mechanix pair is very good for hot summer days at the auction house when you have to drive cars right away while they are baking in the hot summer sun.

    But not nearly as good in a proper winter cold as in below zero. Any time you can get gloves that are insulated you will be much better off. As well as protecting your health.
