Question about 2001 Chevrolet Impala
I have been having problems with my 2001 Impala LS 3.8 V6. Sometimes it wont start for around 10 minutes or so. I almost always have to give it gas while turning the key to start it. I have replaces the starter, battery and fuel pump regulator. Today it actually sputtered and stalled while driving it. It did this for about 10 mins and then went away. I do have some fault codes. Something with the ECU and one with the EGR. I dont know what to do.
ECU is the engine computer and the EGR valve allows exhaust gas to recirculate back into the intake manifold at certain times and is usually vacuum controlled. EGR valves are replaced fairly often because of the high heat from the exhaust. Check for a loose or damaged vacuum hose (or if an electrically controlled valve, look for loose wires, or connector). ECU faults may or may not require replacement of the unit. Have you replaced the fuel filter?
