Just a little data for those that come here via search, I had crazy spark blowout/no code misfires.
I was certain the coils were weak. Brand new ruthenium plugs gapped to .025”
Car purrs and pulls clean with the gap at 0.020”. I’m at sea level, bigger injectors, and Canadian fuel. Our fuel is highly regulated compared to down south. It’s super clean and I frequently have crap fuel in Washington/Oregon
