Today, i started my car and it had a very rough idle. At ~ lunch, I was on the freeway and the car completely stalled. I pulled over and cranked many times just to get the car started. The car had a very rough idle (let's call the symptom 'chugging' like) and would stall upon acceleration from the stop light. I limped to a garage and had a new fuel filter (OEM Bosch from benz bin) installed. The symptoms did not improve. Any ideas/suggestions? intank fuel pump filter clogged? pump pump going bad? TIA!!
