I've got two check engine codes, and need some help with them. If anyone has the troubleshooting steps related to these two codes, could you please copy/paste them here, or maybe scan/email them to me? It would be greatly appreciated! I ordered the manuals, but they won't show up until next Tuesday. I'd like to get started this weekend on checking the car over.
