Try cleaning your egr valve first before anything else, mrnickleye is giving good advice there. Id clean mine for my crappy mileage but I don't have one installed and my bad mileage can be attributed to my recent installation of pace setter headers. the minute increase in performance doesn't compensate for the more recent trips to the gas station. I lost over 50 miles a tank and made sure the O2 sensor was flush when they installed it. Its only back by about 2 feet.
Maybe the performance increase is due to my wallet getting lighter and we all want lighter supras.
