Fluctuating Air-to-Fuel Ratio

Okay cool thanks! By the way, do you know of any gas stations that are actually ethanol free? Maybe shell's V-Plus gas or whatever it is called?

If you have a local fuel distributor, (like the guys who do fleet fueling), you might be able to buy unblended gasoline from them (that's what the ethanol and brand-specific additives are added to). They usually sell unblended gasoline for off-highway use, like for landscape companies to put in their mowers and other power equipment...I know a guy who has a garage full of classic cars, and he buys unblended gasoline for his classics. Somehow, he pays road tax on it. If it is sold specifically for off-highway use, it has to be dyed red to indicate that no road tax was paid on the fuel.

Oh that's sweet! I'll look around and see if there's anything like that!

Hey guys I got another question for you guys! I've been paying more attention to the A/F ratio and I've noticed that the only time it really fluctuates outside of 13.9 and 14.1, is in stop and go traffic where i have to feather the throttle. When I'm in that situation it can fluctuate between 12.8 and 15.3. Any reason why this would be happening or is it normal?
