Question about 2004 Lincoln Navigator
Have you used a NOID light to see if injector is getting a signal, the NOID lite is a little test tool that plugs in the injector connector and flashes when eng is running is signal is present, a vacuum leak can cause this as well, also the injector can be faulty, check the compression 1st, then do the other tests, I was a dealer tech so I had access to a piece of test equip called a SBDS, it could quickly give me all the info about the miss-fire, most case knew the problem in 10 minutes, of course the machine cost $75,000 so in a independent shop it is out of the question. Good Luck
