Expect the shop to tell you it's ASR and they're perplexed. Everybody wants a first time fix but it's a more realistic goal on a non-ASR car. There's no better way to throw parts at it than based on the codes. The alternative to that is probably just to park it.

Ouch!

If you've got a new throttle actuator you're past the worst of it - but there's just a certain amount of guessing with ASR.
