Well, today I replaced the brake light switch with a NAPA replacement and the car runs great. The idle still has a very slight unevenness that it had before.

After looking at the NAPA switch, I'm going to check the dealer.

I cleared all the codes and made 7 "trips" stopping and restarting (to reset the diagnostics as I read somewhere?) and ran at highway speeds and all is good. I don't know if I actually fixed anything or if it's a fluke that will show up again.

But NOW, the heater blower dosn't work!? What could I have done to affect that? I just removed the plastic panel and replaced the brake switch.

Thanks
