There were some cooling issues with the 92's and 93's being charged with a certain refridgerant (I forget the number) but they no longer make it, and if you do find it, it's expensive like $50 a lb (3-4 lbs needed). There were also some probelms with the 92-93's with the distributer failing. Both those problems were corrected in 94.

In all 5th gens though there were some problems with the Oxygen Sensor going bad, it's a $200+ fix through Honda. I'm having that problem myself right now.

Nothing really major to look out for though, a bad O2 sensor isn't going to cause your car to stop working.
