I hope this car has atleast been tuned up lately? and change the Fuel filter before you go digging around since you already have one.1) Check the simple stuff first, vacuum leaks around the intake boot, lines ect...2) Clean the Air flow sensor with Carb/electronic cleaner3) Check to make sure the Idle-Air-Control valve isn't stuck wide open, Bad EGR can also cause a lean problem. Make sure these things aren't semi-crusty and clogging open/close.After these few things are checked? it could get wild and $$$$! Low fuel pressure/Dying or clog fuel injectors/Failing fuel regulator/Fuel pump, MAP/TPS and O2 sensors dying, sometimes these things DO-NOT throw codes till they fail completely.Dig around, check it out</blockquote>
