I have a 95 Nissan Pickup with the 2.4. The problem is it won't start after it has been running and reached any type of warmer temperature. It has ruined my catalytic converter because it runs so rich. It stays at 1500rpm most of the time, but does go back and forth from 750-1500rpm from time to time. I know this must be a sensor problem but I don't know where to start. I was wondering if anybody else had one of these engines and had the same problem. This particular year does not have the dianostic that plugs into a computer to give any trouble codes or else it probably would have been a lot easier. Any thoughts would be appreciated.

Thanks

Mike
