The anti brake light has not come on for two days and about 200 miles. So I have an intermittent issue, but am not going to worry about it. My driving miles for the balance of the winter will be way down so I think I can make it okay.
On another front I asked my friends if they were surprised that I had an OEM muffler [actually 2] in back stock and they said no, they would be surprised if I didn't have a back up...
However when I part this car out I am replacing the muffler [Camaro] on the '88 Black with this newly installed muffler as the exhaust is louder then I like.
