Message	fuel filter air filter thermostat, if open to far or stuck open it will effect engine temp and the ECM will think engine in warm up mode and more fuel will be used at the injectors. Use OEM. This is an oft overlooked item for regaining fuel economy Replace PCV's and special hoses with the interior orifice. Use only OEM Clean the throttle bodies with O2 and CAT safe cleaner Clean MAS and connector and fill connector with dielectric grease Check ECM for codes Check the coolant temp sensor to see if in spec Clean the coolant temp sensor connector and fill with dielectric grease Make sure battery and grounds in good order, Add a ground net system ($10) Instructions on this site Before replacing the O2s check them out fro proper alternating DC voltage. Can use the test procedure noted on this site and read performance thru the check engine light. Also check the heater section of the O2s with a digital ohm meter. See serfice manual for speck I believe it is 3 to 1000 ohms Before prelacing the injectors Ohm them (OK if 10 to 14 Ohms) if OK leave them alone don't look for trouble. Clean the injector connectors and fill with dielectric grease Look for vacuum leaks and fix. You probably have old hard hoses. etc etc etc search for more ZUL8TR in Orlando,FL
