for the past few monhs ive noticed when i driving my truck around 45-55mph nd then WOT to pass a person,as soon as i get around them the truck dies.
i have to pump the gas to get it to restart and when it does its dies again. It takes about 3-4 times f this and it finally runs...i was thinking maybe a clogged fuel filter but i changed it and it still does it...
as long as I drive normally and dont wide open throttle, its does fine.
My truck just started reading a p0420 code but this problem has been occuring much longer than the code has been showing.
the truck has 180xxx miles and has never gave me any trouble...any ideas?
