Well in your original post you said your car was a 94..........in that case you should be fine as long as you have a catalytic convertor to pass the sniffer test.

If you have a 96 and are not throwing a check engine light then you should also be fine.

If you have a 96 and are throwing a code then you are shit out of luck and need to find someone that can turn the code off preminatly

Hope this helps
