Catalytic Converter help!!
 

Ok I'm about tiered of the dealership, I'm on the second trip there and they can't figure out the problem....what would cause my catylitic converter's to heat up and I mean heat up! like glowing red on the top one, they think its a fuel problem but time they get it ,it runs fine when they take it for a test run, there to the point where there so called tech is going to keep it and drive it with the scanner on it to see if it does it again..please help!!

tell them to replace it.. my '87 rx7 has heated up like that and knocked off the heat shield but it still runs fine.. just see about the replacement.. or go to another dealer..
