2004 Impala 3.4 - Stalling and sputtering
My impala has to be flooded to start. Once started it sputters and will stall out unless I keep foot on gas and of course have to ride brake and gas at stops to keep it going.
Even once I am going on freeway I can feel it sputter. Engine light is on and sometimes inks. Code indicates random misfired and oxygen sensor. Could a bad o2 sensor be causing this? Was thinking maybe fuel pump or filter, what do guys think? I don't have alot of money to throw at it and see what sticks. This is just my work car.
This also just happened out of the blue. One day working fine, next day this problem.

Over 250 views and not one person could offer any help. This forum is obviously worthless. In case some poor sap with same problem happens across my post, turns out it was the fuel pressure regulator that was bad.
