OK, I know I am doing it all bass-ackwards. Here is how it happened!:
1. Sticker came due, so I needed an e-test.
2. Car was running a bit rough, so I figured a tune-up would improve my chances.
3. Got tune-up, replaced O2 sensor as it was gummed up with carbon, got new plugs, etc.
4. Thought I'd take a chance with a dodgy cc, but it should have been replaced.
Now I'm trying not to spend any more $$ than I have to! In fairness, the guy who tuned it up is working from his driveway right now so doesn't have a ton of resources at his disposal.
