Thanks to all for the replies. $300 for the cat is a little steep and I did look into the MIL eliminators from Dallas Mustang. I also priced the Bosch 02 sensor at Autozone for about the same price as the MIL eliminator ($57). I think I'm going to try the 02 sensor for now, not sure when I'll get to it but I'll relay the results (at least 2 weeks)
This check engine drives me nuts!
