catalytic converter air pump noise
I don't know if it's because I haven't driven the car in a month, but the air pump tonight after boot up had a very deep trumpet tone... is it on the way out? I've let the car cool down a few times and then driven it again, but it still sounds off and I'm worried. I'm in Florida, and it's 70 out... so don't think it's a temp thing.
Thank you!
Thank you!
