OK, still getting the same CEL problems as yesterday. It only triggers the CEL when the engine is cold, but still doesn't feel so smooth when it's at normal temp. Cold start at idle, smells like gas in the exhaust.

Here are the codes:

more of the story...

Heh, yeah, I know they're misfires.

Basically 3 weeks ago, (40k miles) I brought my car to the stealer, and paid 'em $75 to find out what my CEL was on for. They said "misfire" and offered to change the plugs for another $110. I put in a set of Bosch Platinum 2 plugs for $24 myself, and the light went off 2 days later. I thought I was good. Earlier this week, 900 miles later, it came back on. Ordered myself the VAG-COM, and got those codes. It also looks like one or both of my O2 sensors aren't working, which would make the old, worn spark plugs the result, not the cause of the misfire. The old plugs weren't too bad, though.

Basically, someone told me to paste the actual trouble codes there, since the numbers mean something that I'm not sure of quite yet, since I've only had the VAG-COM for 1 day.
