Yet another Check Engine light question
Today I replaced the two air filter for my car (00 430) as I drove away from the shop, I noticed the my check engine lights are on.
There have been number of threads as what the check engine light is and so on and a lot of them happens right after they change the air filter. But no one have addressed why this happens.
How is it that when you change the air filters, something happens that the MAF or the O2 sensors goes bad.
Any ideas?
Is this going to be reset or do I need to change the MAF or the O2?
thanks

I feel your frustration....as it alsways seems to be the case, but sometimes it isn't. Since you just replaced the fitlers and the light immediatly came on, I would suspect that the airbox was not properly placed back or the MAF clips came loose. Check that first and seal it properly.
Also, I would check the code just in case...autozone or advanced autoparts will check it for you for free. Did you replace the filters with K&N's or OEM?
