I know this is really ignorant sounding ......but what is CATS?...If fishing out a prob in my 87 GXL and some are telling me to check the cats. Im new here and the lingo is something that im going to have to catch up on. Also, thanks to all you guys who graciously answer my questions. This site is awesome. I was really coming close to getting rid of my car because there isnt alot of love for RX7s out here but now i totally am going to keep it. (And maybe get another)

 

Catalytic Converters. They're on your exhaust system.

 

I figured thats what they were.........thanks for clearing it!
