[s-cars] Help! my wife put in 87 octane unleaded yesterday and....

[Mthdealer at aol.com]

The S6 ran poorly last night with very erratic boost. Started this AM ran for 1/2 mile, then loud pop sputtered and stalled. This is when she realizied that reg gas was used. The car will start but just sputter and stall. I thought it would run with reg gas but retard timing. Could the reg gas do this? No time to pull codes til tonight.
thanks,
Dave
