Question about 2004 Infiniti QX4
There are only to Catalysts monitored by the ECM. There is a wide pipe near the front of the exhaust system that looks like it houses a catalyst, but it doesn't. Look for the rear O2 sensor, that is where the catalyst is. If the bolts that hold it on are not badly rusted, and depending on your mechanical aptitude you could replace them, otherwise take it to a shop. Have you checked the warranty coverage with the dealership?

Good news I found out from a forum and it worked for me. Here it is
: 2002 pathfinder sunroof acts up after replacing battery (CKirbyjr) 5:30 PM 5/9/2008
Welcome to NICO -- The same thing happens whenever I disconnect my battery.
Try opening the sunroof all the way (2 inches at a time) and then close it (again two inches at a time). Turn the vehicle off and on again. Sunroof should operate normally.
I'm not sure if the last step is required but I've always done it anyway. It's worked all three times I've had my battery disconnected.

This is due to a loose audio ribbon cable that the CD player feeds to the head unit. If you whack the console on the driver's or passenger's side (lightly) you can get the speakers to come back on. Problem is, it will only get worse over time. Under warranty? Take it to the dealer, they'll replace the head unit. Out of warranty, if you're handy you can pull the radio, find the cable and snug it in.
