Question about 2001 Toyota Corolla
I have a 2001 corolla myself with the check engine light on for awhile. these cars are notorious for having bad o2 sensors and Mass air flow sensors. These are parts that help the engine utilize gas properly, basically energy conserving, pollution reducing parts. From my experience the car runs fine with the light on as long as it is these problems. You could take it to an autozone and have them run the codes for you and you could make sure that is the problem, but i have read a lot of forums that speak to this issue. you can also clean the MAF sensor with some Electrical cleaner (found in auto section of Walmart). Goggle the problem and you can find step by step toturials that walk you throught DIY process. It is really simple actually. The O2 sensor might need to be replaced make sure you get the OEM part and not the universal.
