[Shotimes] Help with lean condition

[Mark Helpinstill]

Kris and George,

Thanks for the suggestions.

Definitely cleared the codes each time.

Checked Bosch part #s online and at the store - seems to be correct.

Not willing to spend $500 on new cats.

Looked for vacuum leaks again today and found nothing.

Looks like I will be pulling the spout connector and hoping for the best.

Thanks
Mark
