Default Can I pass PA emissions by using O2 simms?

Ok, live in a PA and have an all stock 01 Firebird. Mechanic says it needs new cats to pass emissions.

Is it possible to use a set of O2 simms to get ride of the SES light and get me through emissions?

Thanks!

It depends what county you live in. There are only two places in pa that can pull that, and thats if you live in Philly or Pitts. Other than that the light has to be off, if he sees its on and its throwing a code he doesnt have to pass it. if it is the o2's get some new ones get it fixed and your good to go. Cats wise what do you think. I doubt you need now ones. They might be after your visa card if you know what I mean.

What code(s) you throwing? If it's P0420 and P0430 and you're under 80K stock cats are covered under the federal emissions warranty.

As long as it's your rear o2's throwing the code, just reset the PCM, install o2 sims fire it up and the computer will never know anything is wrong. You could also find a tuner who could do the same without having to buy o2 sims..

+1, but don't keep bad cats in there long. Car will start to smell and could lose some power due to the crap rattling around in there. Get some high flow replacements, or possibly take this opportunity to get your exhaust done.

Got 120K on the clock now, and it already had the cats done under warranty at 60K.

I know its not the right long term fix, but just want to get it tagged for now.

Thanks for the help!

I run an offroad ypipe (no cats), 02 sims, and I live 20 minutes outside of Philly. I tuned the DTC's to not have the SES light come on for: !EGR, !AIR, !rear 02s. I had no issues passing emisisons.

Good luck
