I have a 2009 HHR SS that was tuned by BYT. It has a ZZP Catless down pipe and failed Pennsylvania state emissions testing. I thought that tuning would take care of this? If I have to go buy a GM down pipe then I guess I will have to, but I cant keep taking my car back and forth and paying for failed tests.

 

What did you fail on ?Did they tell you?
Can you scan the sheet and post it.

High No2?
High carbon ?

 

Catless = emission devil.

Here are your options:

1. Go to a county that DOESN'T do emission testing (Monroe) doesn't.
2. Find a shop that will pass you regardless for couple extra bucks.
3. Get a catted DP, pass inspection.

 

Apparently the senors that say whether or not the car is ready yet for emissions testing after clearing a check engine light are not ready?

 

They are the drive cycles and can take some time to get through.
Hard lesson learned -clearing codes and going to the emissions testing doesn't help the cause.
It's better if you have a code befor emissions is to find out the code and not erase it then fix the problem and let the code go away on its own.
This usually only takes a number of starts.

 

IM in the same boat here in MA. trying to see what i can do to make this work

 

I didn't think York had emissions. Going to another county won't help, the inspection is based on where the car is registared. If they sent you away for "not ready" then you didn't fail, your ca just wasn't ready to be tested. If you haven't cleared a cell in a while it could be tune related. Best bet drive the **** out of it, lots of miles, shirt trips, long trips, everything in between. Then go to an autozone or something and use their code reader to see if it's set all the readiness codes. I live in an area where they do emissions, like you, I have one of those O2 extenders, no problems at all.

 

Spend a few bucks on a code reader that tells you if the drive cycles are ready,the one I have does it and codes and also graphing.
Looking at the newer version that has a abs option as well.
Well worth the investment,it pays for itself if you repair the car once using it.

 

York has a OBDII emissions test. Its just the basic emissions test. No visual and nothing to actually test the exhaust quality. The car has been driven at least 400+ since tuning. Monroe county to philly, then york, Baltimore, state college and back twice. I didn't know auto zone (or any store) could pull the readiness status? I have an OBDII reader and it doesn't have any faults or CEL to pull. I ordered a piece from modern performance to keep the o2 senor out of the main stream so in worst case scenario it can be put in and my car tuned back to normal.
