I just had the injectores flushed and just cleaned the K&N.</P>

How can I tell if the cats are bad, they are OEM.</P>

Also, how many o2 sensors are their? Thanks</P>

I'm not sure how you'd test the cats - emission test perhaps? That'd tell you if something is wrong anyway.

There are 2 O2 sensors, and for my 91 gt they ran about $90 for the pair.
