Lately my car has been giving me issues on a cold start...it turns, then starts, then immediately cuts out.after it cuts out all the dash lights come on, I then restart it and it works just fine? I'm replacing the map and cam sensors and maybe the fuel filter...I did the crankshaft like maybe six years ago and recently replaced the maf. Any suggestions or similar experiences? The Mercedes forums are leaning towards k40 or battery cables being corroded?
