Mick Blankenship (Buickgn38sfi) | Friday, October 18, 2002 - 06:11 pm I have had really good luck with regular AC DELCO plugs set at .035 However,..I suggest that you use AUTOLITE @ the same gap... If this does not help...you need to check your timing,..then if it is correct, then your injectors probably need to be cleand (sonicly) Remember,...these cars dont wanna run on anything less than 93 octane. This is what I would start with. |
