LOL... you know these things just don't fix themselves.

Did you check anything over the weekend?

My advice remains the same...

I would start by pulling diagnostic codes...

I found a great article on how to test for codes.

This will be of particular interest to those with 1984 through 1988 models, but is also excellent for those up to the 1995 models.
