Question about 2002 Chevrolet Silverado
My 2002 chevy silverado with 145,000km struggles to stay running when stopped and idling. It boggs down like its almost being smothered (lack of fuel or something) It has a brand new fuel pump and fuel filter. My check engine light is on constantly.
I had the same truck and it had lean codes.
The intake gaskets go bad causing too much air to enter the chambers. ITs the same gasket for the 4.8 and 5.3 litre motors.
upon tear down i found the fuel pressure regulator had fuel in it indicating the diaphram went bad.
Fixed and everythings all right.
BUT check your codes first I don't want to you to do a tear down with out knowing what the computer is doing first. Auto zone does free diagnostics and tell you what the codes are. Let me know I can guide you from there.
