ok so when i start the car its starts just fine but has way to much unburnt gas coming out. i did a scan and all it found was fault code p1550 which is cruise control not engageing. whenever you drive the car it stalls and dies about 2 min after you stat moving. just wondering if you know where i should start looking

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.

Ok thank you for the input. So aside from just replacing parts is there anything I can do to eliminate some of the possibilities? If not that's cool ill start shopping around
