I told ya I frequent the same establishments.. I did have a fuel leak around the tank gasket but its been fixed for a few tanks. I'm thinking I may have plug leads or cap/rotor problems. It is rock solid idling though. I am going to try and do compression test over the weekend and see if that may be a problem. At cruise I see a repetitive drop in a/f ratio as in one poorly firing cylinder. Hopefully nothing major requiring a tear down..
