^^ It is a 5 minute process of plugging there sensor into your port, and letting you know what is going on with your engine/emissions. Would be a safe measure, then driving around in your car with a potential malfunction on your car, and waiting 5 days and continuing to do damage.

But hey, to each their own I suppose.

 

Watch them, they won't "monkey" with it .... I wouldn't allow Pep Boys to work on my car but I think they can handle plugging a scanner into a port. I don't get it either, you have been posting for days about your code and what it means,etc. Just take it in ....
