Thanks, for the information on the o2 sims. I looked at the exhaust closer this weekend, it looks like I have the dual cats, therefore I believe I need a sensor that is dual in, and dual out. I checked the codes, and it is showing codes for all four sensors. I haven't had time yet to check to see if the sensors before the cats are reading properly. As I understand they will have to be operational before the simulators will do any good. Other than that I was able to fix some of the other misc things that needed fixing. Drivers door panel flopping around, passenger door speaker that didn't work, and adding some mud flaps. I got it shined up and shot a few pictures at the shop, with the 85.
