Question about 2000 Toyota Corolla
Mass Air Flow sensor! Just remove your air filter cover. Go to Auto Zone and purchase some solvent. Spray past the air filter and it should correct the problem. If not, replace the Mass air-flow sensor. This is commonly mistaken for an oxygen sensor. Mine did this and I followed these steps and it fixed the light. BTW, the light stayed on for 5 years before I fixed it. Never hurt anything. It's normally something to do with emissions. Dummy lights. :)

Unfortunately I had the same exact problem on my 2001 Toyota Corolla. I also replaced both oxygen sensors with no success. I actually had to replace the catalytic converter. Worse I had to go thru the dealer . Midas told me they won't replace Corolla converters . At least the problem is solved.

With the MAF use CRC electronic cleaner. it is designed for this use and will not leave residue. it should work but either way this problem will not be bad. i have run years and 1000s of miles with that engine light on due to a bad o2 sensor. Luckly i dont live in an emissions state.
