I have a 2000 Toyota Corolla with P0171 code. At first, I cleaned MAF sensor with a cleaner and cleared the code, but the code came back on the next day. The second time, I thoroughly cleaned (Only Spraying the cleaner more thoroughly) MAF sensor again and replaced the Air Filter, but the code came back again. It seems that the code only appears when I drive local (less than 45mph) for about an hour or so because the code never came on when I was driving on the freeway.
have the same problem?
