Alright, so I've been running the 75 shot for awhile, basically, everytime I use it, my CEL comes on. I was resetting the ECU by disconnecting the battery and everything would be fine. There would be no side effects whatsoever, just the CEL would come on. Now the other day, I hadn't reset the ECU yet and went to go get gas. So I filled up and did the three clicks or more on the gas cap, start the car, and bam, no CEL.
So anyone have a clue on why my damn CEL comes on?
Will it come on if I run rich when spraying?

Thanks
