[s-cars] Mistery miss

[Robert Voytcheff]

Calvin,

Thank you for the advise - this is the most logical and practical way I
thought of, and despite having been quite successful using it in the past,
it did not work earlier today. There was absolutely no difference in the way
the car ran, it only triggered codes for the injectors afterwards.

Regards,
Robert V.
