Failed PA State Emissions Not sure why yet. I have to go pick it up at 5pm. Air filter is dirty as heck. May be an issue? Oil hasn't been changed in I'm guessing 6k miles (been running Mobile 1 Synthetic though for about 5 years .. prev. owner included). Has a cat, though it's high flow.
I recently had the vehicle tuned at a performance shop. Spoke with the previous owner and he said it has new o2 sensors, EGR, plugs, wires, etc. I'm thinking the tune caused it to fail. I just need to wait and see the #'s to see what failed.
Any help before that point is appreciated, but I guess this is more of a rant 'til I find out what the deal is.
They told me Safety passed, though, and to bring it back once it passes emissions and they will sticker it.
EDIT: Failed for CO. Everything else is fine. Info...
CO % x liters...
Limit: 1.1
Test Value: 1.82 (00.32%)
Like I said, all else is good. Idea's?

Yah just make sure you aren't throwing any codes or it's a failure for that too. It depends what counties as well. Some of the more rural counties don't have emissions period.

I thought the cat was supposed to take care of the CO? Correct me if I'm wrong. But if I'm right, it sounds like your cat isn't working fully or perhaps you are a bit on the rich side. Of course, putting a new air filter in so the car can breathe might help too

I didn't check the air filter 'til someone mentioned it. I didn't think it'd have an issue passing per the previous owner. 6k miles on synthetic isn't a big deal.

The shop I had it tuned at before the emissions test told me it was running rich. So I am changing the o2 sensors as discussed.
