hey guys...this has been doing this for the past 3 days or so. ive noticed when i drive and at a stoplight or whatever the truck would shake or jerk a lil bit. didnt think much of it since i thought it was my flowmaster exhaust. whenever i switch gears from D to Park, the engine cuts off. or if i go from reverse to Park, it cuts off. seems like the air flow is hesitating or whatever..any suggestions??? like tonight, went to wendys drive thru, the guy told me to pull foward and wait till he brings out my food..so i drive up about 20 feet, then put my car in park.next thing you know..it cuts off..HELP ME PLEASE..i have an 03 ram 1500 SLT 4.7magnum
