first let me say that i'm a dope. i noticed a few months ago that my V8 was running really crappy. i have been chasing the problem for a long time, mostly adjusting the carb mixture and idle, and changing vaccuum hoses. anyway-i noticed today that one of the spark plug wires was touching the header and that it had burned it completely through. i have been running of 7 cylinders for about 2 months. anyway- got that fixed and we're back to normal. i could kick myself in the shorts sometimes.
