I was wondering if its possible to only run rich while idling, and not during driving. I get average mgp as long as I never let the car idle. But as soon as I let the idle, even for just 10 mins, that tank of gas will lose about 35 - 40 miles from the total number of miles I normally get to a tank. Am I imagining things, is there something I can do to diagnose?
