Default Failed AirCare, Running Rich?

I failed my emissions test…. Badly! HC and CO are through the roof. I’m not surprised. I’ve been having real starting issues for a couple months. Doesn’t want to catch and when it does, I smell fuel. She’s also low on power and idling rough.

Any idea on where to start? Plugs or sensor? She’s an 1989, stock. Time for C6?

You need to scan it to see what fuel delivery is - until you get an idea, it's all a guess.
