Back in Feb. went through a bunch of really deep snow and my truck started to sputter really bad. Well since then it has gotten better but still does it about evey other time I drive it. No check engine light so not sure what it is, but i think it is something that is low on the truck because it started when I went through the snow. When it first started to do it I popped the hood and the c.o.p wasnt wet at all so im thinking it had to be lower on the truck some were. 99 v10 118xxx 4x4 Thanks for any replies.
I picked up a 99 V10 4 weeks ago. It had a sputter/ missfire. Ended up I could hear a tapping when I first started it and got out of truck, then it went away, then I heard it again. Quick opened the hood and got a milk crate to stand on to get in close. As I got closer I knew it was not a typical mechanical lifter tap but a electrical arch snap. I then found a coil bolt loose and shut it off. took the bolt out and pulled the coil. Low and behold the boot was split up the length part way and was misfiring out sideways through the crack. I replaced the boot and it immeadiately ran smoother at idle and the occasional stumble on highway is gone 100%. Well, that is my story anyhow.
