This may sound like a stupid question but you never know until you ask....Can a computer detect issues with a fuel injector and disable it or randomly send signals if the injector is damaged? I have a 2002 Sable with the 3.0 OHV motor. Same as a Taurus for the most part.. A while back I lost cylinder 5 while driving. Made a lot of pinging and misfired badly. What I saw was that the spark plug had lost the platinum tip and it was apparently banging around until I could get stopped. I replaced all plugs and wires and find it has a bad misfire at idle. Not at normal speeds though. I checked and found the injector is "clicking" half of the time. About 30 seconds or so of every minute at idle it simply does not work. Thought perhaps the injector was damaged but I hooked a noid light to the cable and the pulse is random. Seems a bit much of a coincidence that something else would be wrong so am curious if perhaps the computer may be detecting issues and sending a random pulse. of course that does not explain to me the random flashing of the noid light. Like I said, may be a stupid question but had to ask.
