After looking for clues as to why my 93 Camry gives not-so-good gas mileage, my mechanic recently found that the EGR Vaccum Modulator (not sure of the right part's name) was not fonctionning at all. Any opinions out there? Anyone knows where I could find a used one for a 93 Camry 4cyl. by any chance? A new one is 110.00 CAN$. Ouch! Thanks guys.
