Emissions problem

[vorstang]

I went to get my car inspected and it failed the emissions part, 02 sensors not ready,egr not ready, ect.. I think they were turned off maybe, with the tune in the car. It came from P.A. Any thoughts?

I believe you're only allowed 1 "not ready" for your year to pass.

How was it tuned? Did you get a tuner with the car?

I would think having the O2's turned back on in the tune (if that's the case) and running MIL eliminators for them would drop you to just 1 "not ready" (the EGR).


Of course I'm only throwing out guesses so hopefully someone that actually knows what they're talking about will chime in.

What exhaust is on the car? If it hasn't any cats the rear o2 are turned off. If it has headers some delete the egr. It is on the passenger side of the blower closest to the firewall. check to see if there is a tube going to it or if there is a blockoff plate.
chances are the tune from pa is from evolution performance in Aston pa.
Mil eliminators do not work with the s197 computer for some reason.
