yeah, i as well. but if the alternator is going bad, which it sounds like the problem is, keeping it revved up wont matter if the alternator is quickly degrading. now, if at higher rpms its still able to produce enough voltage to run his headlights, produce the sparks and everything else he needs done then yeah, drive home. sometimes, with a bad alternator, thats not possible. i spent the night in milwaukee in 2001 because of a bad alternator, and i knew it was going bad and was trying to get home, keeping the rpms up and such.

wow, the crackheads that walk around downtown milwaukee at 2 in the morning...
