Tried to change just one pack but that was only an incremental improvement so I changed them all, since I had been receiving a random misfire code. Much improved but still throwing a code PO303 but now it is specific to cylinder 3 which now gets me down to either a fouled plug, a bad wire or a dirty injector. Will address that tomorrow along with some other issues.

Did some scans and LTFT'* are still going as high as 16.4 on any deliberately brisk throttle application, although the STFT'* only fluctuate between maybe -3.5 though +5. They all drop to 0 on 0 throttle which is better than I was doing with the previous engine.

If it doesn't rain tomorrow maybe I can give the engine some more attention like the supercharger fluid, thermostat mod, change out the fuel filter, etc.
Any suggestions or comments are appreciated.

Agreed on checking the plug, wire and also check that coil post. I've actually had a single post go bad.

Found out it was a broke plug

Wow, last time i saw one of those plugs was when i was spraying. Were you spraying?

Its an AC Delco Iridium, I don't understand the spraying part, please clarify?

Spraying as in Spraying NOS!!

i know is a AC Delco plug

Thanks I just learned something, kewl. At first I thought you were referring to some kind of gardening operation as people like to tease me because I like Champion sparkplugs.
