Hi, I have a '99 Eurovan camper that seems to be blowing fuel injectors. Here’s the history:  
  
  
  
 1. One day the carbon monoxide alarm went off and I realized that the deep cell battery had discharged. I drove the van around and the battery charged but after being parked for a while, the alarm sounded again. At the same time, the check engine light came on and the van started driving rough.  
  
  
  
 2. I brought the van to the mechanic and the scan showed that fuel injector no. 5  
  
 had an electrical fault. The mechanic also determined that the alternator was  
  
 bad. He replaced the alternator and fuel injector no. 5 and it seemed fine for  
  
 a week of around-town driving.  
  
  
  
 3. I drove two hours and the check engine light came on and ran rough again.  
  
 The scan at the closest VW dealer showed that injector no. 4 was bad. I drove  
  
 back to the original mechanic and by the time I got there, the scan showed that  
  
 No. 2 had gone bad also.  
  
  
  
 Replacing fuel injectors in the van is very expensive and I want to make sure that whatever is causing them to malfunction is fixed but the two mechanics don’t know what the problem could be. I don’t believe that it’s a random occurance that fuel injectors are all malfunctioning around the same time. Any ideas??  
  
 Thanks.
