P0172 check engine code in '98 Prelude SH

So I have a problem with my car stalling at stops or when I let the engine wind down. Could this be my fuel pressure regulator or something else. Any suggestions for a good cheap fix? The engine is a 2.2L VTEC with about 150,000 miles on it.

Try checking the following:Possible causes include a bad O2 sensor, excessive fuel pressure (bad fuel pressure regulator or plugged return line), leaky fuel injectors, dirty air filter or restricted air inlet, or a defective coolant sensor that prevents the engine management system from going into closed loop mode.
