While we are on the subject of air care. I thought they were going to toss it. If you have a car with an OB2 in it, they plug in the OB2 reader and check for codes. Then you give them $45. It takes like 10 minutes at the most. What a rip.
Couldn't I be sitting in my truck with my reader and clear any codes just before I drove in and the codes would be gone?
