There are alot of things it COULD be, but I can't give you a definite answer COULD be bad fuel. COULD be dirty fuel filter. COULD be dirty injectors. COULD be a hole in the fuel line allowing it to suck air. A trip to the Ford garage so they can put an analyzer on it and take it for a drive might be a good idea.
MINE WAS DOING THE SAME THING AND IT WAS THE EGR VALVE!! THAT FIXED IT AND IT'S RUNNING GREAT!!:)GOOD LUCK
No. They sputter for a few seconds then quit running.
It may be a EGR valve issue. This valve is normally closed at idle and opens at about 40mph.
They start to sputter,stall and stop running.
No
You Probley have a blowed head gasket.
Oil sputter is going to be a normal thing if the oil cap is not on while the engine is running. The engine should never be run with the oil cap open. The engine actually has less compression when the oil cap is open, and this could hurt the engine.
I have a 2003 mercury grand marquis will sputter around running 35 - 60 mph ?
I expect the motor to sputter to life any second, now... The clerk was so exasperated, he could only sputter.
My camero doesn't sputter ever, even when you accelerate.
