I have a problem with one at work. I am hopeing someone out here will have had the same problem, but skeptic. I have a 99 Lumina (same engien and parts as 97) that is defiantaly not fireing on #6. the plug is good, the wire is good, the injector has been swaped around to see if problem followed, and the O2 sensor was checked, and I did a cylinder pressure test. All checked out great. I have even gone so far as to swap EGR valves out with another sedan. I checked around by sight and hearing and the vacume seems good. Same thing, missfire #6 while watching with the scan tool. Does anyone have a solution? I am Air Force and running out of time. The cops have put about 300,000 miles on this thing. Any advise that is within scope would be greatly appreciated.
