There it is, those plugs are very confused.
Are you running fresh gas?
Are you saying what I'm reading? that
The throttle blades are completley closed?
I drive the car pretty frequently, about 1200 miles a year in warm weather. It will sit through winter though. This road trip was on gas filled up that morning.
Yes, I've been setting the hot idle all the way down and setting timing by advancing to where engine has highest vacuum. I have been setting the idle mixtures by slowly closing until vacuum drops off than back it off and giving it another quarter turn open. That tends to leave hot idle right at ~650-700 which is factory. I've not seen a comprehensive method of setting timing, idle fuel, and idle speed, in a tune that considers all of them together for a driver so this is what I've picked up from the various sources that seem to vary wildly on "how they do it" for their car that is often modified and are tuned for high end power.
