I HAVE THIS 2001 TOYOTA COROLLA, AND IT'S TAKING TOOMUCH GAS, AND THE MUFFLES END GOT LIKE ALOT OF CARBON BUILD UP. WHEN GOT IT INTO A STOP AND THEN STARTED OVER STALLS. I'VE CHANGED 1 SENSOR, SPRK PLUGS, AIR FILTER, CATALITIC CONVERTER, AND NOTHING IMPROVES GREATLY.

Hi there,

Do a fuel rail pressure test to check for a leaking injector and have the O2 sensor checked as if it is faulty it will induce a full rich mixture. Start there.
