I'm Awesome
Yes MPFI upgrade. I couldn’t remember what it was called. After It ran phenomenal. I had no idea it would help so much. Usually runs awesome. I put new plugs in yesterday. I just checked the plug. It’s at .06 which is what I gapped it at yesterday. I just checked the plug and it has spark. I don’t have any help so I set my phone up on record and turned over the ignition and went back and watched the video. It’s got two arc’s on it. I think the one that shouldn’t be there just grounded out through my gloves. I will go and rent a fuel pressure gauge tomorrow and return it when done.
so this is all on passenger side which is bank two. When I removed the plugs on bank two yesterday they were all worse off than one bank one.
I think there's your hint there. Bank 2 is running very rich at idle and you seem to indicate the plugs on that bank are fouled, right? With fuel? Sometimes dumping too much fuel on a given cylinder can cause misfire. I suppose too much fuel overwhelms the spark and air ratio? I don't know.
BTW, a flashing CEL light usually indicates indicates a misfire (misfire bad enough such that your catalytic converter can be damaged).
Coinsidently, at 3,000 RPM (when you actually NEED more fuel), the fuel trims seem to improve. That's what I'm hypothesizing; you'll need to prove that somehow....
How long ago were the injectors replaced? Maybe an o ring is leaking internally?
