I got the code wrong from the book it is the code P0171 or something like that, the mechanic looked at it on Friday and found that the PCV valve was bad and it had been letting oil into my air box as well as other parts of my engine, he aslo thinks that the computer that helps the engine now how much oxygen to let into the gas is bad. I will keep you informed on the repairs. 00Avalon

I own a 2000 Avalon and I believe that the in cabin air filter in my car is dirty, the reason that I believe this is because there tends to be a lot of dust and other stuff that accumulates on the dash of my car. I wipe it down clean and then a week later the same problem. I was wondering if this was the in cabin air filter or if it could be something else? If if is the air filter if anyone could give me the steps on how to change it, if it is not suggestions on what else the problem is would be appreciated. Thanks, 00Avalon

My check engine light has come on three or four times reading the same code, P0101. I believe that this is the code for the oxygen sensor in bank one. This is what I have been told each time I get it checked. I have been told countless times that by changing the O2 sensor it would fix the problem. If there is anyone that could give me a suggestion on what possibly could be the problem that would be great. Thanks, 00Avalon
