Firestone no sucsess pulling codes on '94 Chevy Camaro
I wrote on here about a week or two ago about my '94 Camaro not giving off any codes. Took it up to Firestone and I'm on my way to pick it up now. They told me they cannot figure out why it won't read. Told me how they had multiple people look and try, and they can't get anything. They're referring me to a dealer now and there is no way I'll be able to afford an appointment with them and then parts after. Any suggestions? I'm told it sounds like a cylinder is misfiring and the car runs rough.Already rereplaced spark plugs. Didn't change anything.
