Re: "Sevice Engine Soon" days after air filter replacement
You can either choose to reset your ecu or just keep driving it and the "SES" light will go away. I'd rather that you reset the code with an OBDII code reader, that way, your ecu map doesn't have to start over. It takes about a week or two of driving for the ecu to relearn. What probably happen was your air filter was probably dirty as hell for a long time and the ecu got used to it. Then when you put a clean, more free flowing filter on, the ecu threw a code saying it's getting too much air because of the improper installation and freer flowing filter. Nothing big to worry about. If this is all you did, I wouldn't mess with the maf, you might damage it and it will cost more money to have it replaced.
