hey all got a 1995 E250 inline 300 6cyl--E4OD trans we had a ton of rain a few weeks back the van began shifting way hard like someone ran into the rear of it and was running like crap--stalling from idle hardly idling --just not able to drive it --turns out after countless hour of checking things --the aftermarket MAP sensor had water in it --it mount high under the hood just below the windshield cowl area-- guess the seal it seems where they put it together was no good -just a FYI if anyone runs into to this crazy issue on theirs--had me stumped for a few days -
