I ran into something very strange today. I bought oil stabilizer fuel treatment. I put all that in and when I got home I tried something. When the cel started to flash I played around with #5 and #6 fuel injector connectors. I took #6 off no difference then took #5 off engine drop a little. Then I put #6 on #5 no difference. Then I put #6 back on and was playing with it with #5 off. All of a sudden #6 started to fire after about 30 sec. Then I put #5 on the engine would run on all 6 for 15 sec then die off again. #6 missfiring again. Has anyone had this problem if so what was it.
