Feel free to jump in with some advice.
I cleared the codes and we'll see if they come on again.
FWIW, on cold start-up this morning, the air pump did come on and ran for about a minute and a half before shutting off. It's makes a lot of noise, but it always has.
I hope it's not the darned air pump, because Phil at PartsShop sells it for $967.51. I don't even want to know what the dealer charges.
Does anyone think perhaps the hot, hot weather confused the system and the pump didn't engage just once or twice?
I have this weird luck that the only parts that break on my car all cost about $1,000.
