2001 Daewoo Leganza fuel problem. I have been having some trouble getting my car started in the morning since the weather turned cold this year. I had an oil leak around the valve cover so I replaced the gasket and went to get some gas (almost on empty) As I drove down the road, almost 2 miles, I noticed a sudden loss of power. The car would idle but any time I would try to apply power the engine would bogg down. I got the car home and thought this was possibly a fuel filter problem so I tapped on the side of the filter and it seemed to fix it. I replaced the filter the next day only to return to the original problem. 1. Hard to start in the morning. 2. Engine seems to bogg down but improves the longer it runs.

Check the fuel pressure with a gauge if its within specs-if so test the coolant temperature sensor-bogging/hesistating could be one of the below

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.

Note:If it doesn't apply disregard it and keep testing
