So I have been having fuel delivery issues and this week I changed the fuel module, pump and filter, after it runs fine and better however when coming to a stop the rpms drop way down and the truck starts to shake and knock badly! Then when I give it gas it stops and runs fine after a few seconds, if I let it start doing this and don't give it any gas it continues until throttle is pushed...... Please help! Here is a video, it sounds loudest at the top passenger side!
