checked the distributor .. it's still nice and tight.. all I did last night was pull a couple plugs and see that they look like this .. I did check in with the guy who dyno'd it and he's thinking it may be caused by the winter fuel mixture here in CA - says a lot of guys' cars run like crap on it..and the deposits on the plugs are most likely from the crappy gas. and now that the weather is cooler (70's), it might be running a bit leaner .. he's going to check his notes from our tune and give me a recommendation on different metering rods to help the AF ratio.

Unrelated .. something is spraying on the front drivers side of the engine ... not sure where it's coming from ... there's not really anything over there! White deposits from... something.
