SMELLS LIKE IT IS RUNNING RICH FUEL MIXTURE

1996 SAAB 900

Smells problem
1996 Saab 900 4 cyl Front Wheel Drive Manual 152546 miles

Hard to start. Seems like it is starving for fuel. Kicks over run for a few seconds and cuts off. Takes several times for it to start and idle. Once idleing have to let run before driving for a minute or two.
Can injection run rich? I just got the car replaced the coil and now this started. It started sputering going down the highway which caused the check engine light to come on. I just don't know what to check.

Any Help would be appreciated.

what can you spray the ignition switch to keep it from sticking?

Thanks in advance

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.
