I just got a 2003 Sprinter with 170k a couple weeks ago. We are on a family road trip and having weird issues. After getting a new EGR, engine computer, fuel hoses, and crank shaft sensor and cam shaft sensor, it ran beautifully for about 3 hours on the freeway. Then as we came off the freeway and turned left it stuttered or bucked. The fuel tank was at half so we topped it off and then got back on the freeway. For the next hour it occasionally and sporadically would stutter till we decided to pull off and get a room. Coming off the freeway and turning it did it again and again so we barely got to the hotel. When my wife went in to check in, the van stalled while idling. After many tries and about 20 minutes it restarted barely and stalled 3 more times before I got it parked for the night. I checked but saw no air bubbles in the fuel.
This morning it started and ran fine in town. It ran fine up and down the freeway, too, till I got off. Then it started stuttering again and stalled a few minutes later at a stop sign. I sat there in the way of traffic for about 20 minutes till it cooled down again and I was able to drive it the remaining half mile to a dealer. The check engine light did not come on. They will look at it later today.
Any ideas? I am leaning towards a wire harness chafing, but the previous mechanics didn't see anything like that. Could it be the DPF? A cracked tube in the fuel tank? The EGR couldnt have gotten dirty in 300 miles, could it? The injectors looked fine a few days ago, according to the diagnostic software.
