Random M54 Misfire on Random Cold Start checklist...PROBABLY SOLVED

[Ricky Bobby]

I may have gotten off the wagon a bit - I have no vaccuum leaks now but want to preventatively replace some of the associated vaccuum tubing due to age - totally different issue

And the rough "washing machine idle followed by SES light" only has happened 4 times in the past year - apparently its a random Misfire on Cyl 6 with fuel cutoff - which could have its own symptom needing to be fixed, or as was mentioned earlier with jfoj - could be me just pulling the car out of the garage followed by pulling it in and not giving enough idle time to burn off the startup fuel that has primed in the rail, effectively flooding a cylinder.

Will keep you guys posted but the VCG and vaccuum tubing/caps replacement was more of a "well its probably time to take care of these things" - but not necessarily 100% required in the moment.

Besides oil changes and PS fluid reservoir and fluid change, I really haven't done any other maintenance in the past 2 years and she has been running great.
