I have a 92 Q, orginally from CA. Can any one tell me what/if there are extra CA only "performance robbing" devices on this car?

The car now is in MN, and only run on sunny summer sundays.

All in ecu software program..........nothing different mechanically except some had an extra sensor to measure EGR gas temperature. More codes possible to illuminate MIL.

I believe the catalytic converters are a different part number, but that's the only other difference I know of. I have a CA Q but I'm running the "NICO ECU" in it.

Thanks,

Heath

i believe the CA models had an extra coolant temp sensor under the plenum too.

My current Q is a standard one, my old one was a cali car, and its basically the same thing. nothing that would affect the performance for sure.
