Perhaps I celebrated a bit too early, or perhaps I'm just unlucky. The check engine light came on driving around town today. Cam shaft position codes. Not a faulty sensor, but one code for over advanced, and one for under advanced. Car doesn't appear to be running or idling rough, but since I had to undo the VANOS line and the electrical connections to the VANOS solenoid, I'm wondering what I screwed up.
I've cleared the codes and I'm about to run some errands so we will see if they come back.
