1999 CHEVY 1500 4.3 SHUTTERED AND DIED AT IDLE..
My sons truck died at a stop light. Would start after several seconds of
cranking and giving a little gas. Ran very rough. However, only with high
rpms would it keep running. Idle and would vibrate and die.
I was checking the Mass Air Flow Sensor when I found water in the air
intake tube between the MAFS and the Intake. Then I checked the oil and it
was milky like water in oil. Then the Radiator over flow tank was low.
I was thinking probable intake gasket. However, what would cause water in
intake tube?
Do you think intake would happen suddenly like that?
Any suggestions would be appreciated.
