FWIW, after I got the first CEL I took my car to the shop for a full day of diagnostics. They used the Porsche PS or whatever that crazy expensive thing is that looks like an old Etcha-Sketch. While they were able to get the same fault codes, they could find nothing else wrong, other than low voltage in one O2 sensor and actually a rich condition by putting a probe in the tail pipe with the engine off and turning it over by hand. So the lean condition fault code was totally untraceable. Am I right to assume that I'm causing no damage by driving it if it runs and sounds fine? I can't tell if my fuel economy has gotten better because the last entire tank of gas was 100% highway miles and a lot of it in 6th gear or because the LubroMoly cleared out a sticky injector or what exactly happened. My temps run a little high when driving in stop and go traffic on a super hot day. Needle gets to 9 o'clock. But on the hwy. with the a/c on it goes down to about even with the first tick mark.
