My '92 190E 2.6 began intermittently stalling at start up after driving when put in drive. It would start up and go after a short wait on those occasions when it stalled out. Yesterday it died going down the road after 5 miles and would not start. Had to have AAA flat bed me home. Today it started right up but I'm afraid to drive it. I'm thinking OVP? fuel filter? Ideas anyone?
