We have a radio show on Saturday mornings called Greg's Japaneses auto. They talk about all cars on there and when ever I can I turn it on to try to learn.
I'm really far from being a mechanic. LOL!
Over the years I have tried to learn so when something goes wrong I can help myself with my communication with the mechanic.
I feel the more you can tell the mechanic better off you are so they don't waste so much time in certain situations.
Also purchased myself a code reader which has helped also.
