So it's a Mercedes then? Lol, just busting your ***** man. I just got rid of a Dodge actually. We bought a new car for my wife, traded in the Durango I was driving (it was a POS) and now back in my F150. It's a long story as to why I was in that Durango to begin with, I missed my truck badly.

lol my mom had a durango and theres a reason thats gone and she has what was my f150, my first truck was a 95 dakota and haven't had a problem with any of my trucks, never going to chevy though lol mom and dad both did that and i wasnt a big fan

Well, your a good sport. I don't care how many plugs you have.

Anyway, how many miles do those plugs in the back have on them, any idea ? I'll assume those are Motorcraft. If it's misfiring after about 45 mph plus (common), the misfire count may not be high enough yet. But , or and, - if the gap is stretched out from wear on the back two, it's not going to run very well. Number 4 and 8 might not be so bad if you flip the fuel rail up and onto the intake. I always do, - I hate crap in the way. If you decide to do that, lay some rags down around the coils and injectors first!

IMO, you should be able to determine or distinguish a misfire problem driving it. Didn't you say the problem doesn't happen with you driving it, - or haven't you had the chance yet ?

they are motorcraft, my first change was 80k so they all have 10k miles on them except cyl. 8 which which ide guess sits at 40k, idles a little rough but just enough to notice, i finally got to drive it for a 100ish miles, and i dont thinks its a misfire persay, as i get to 50-60 mph, i feel as if i just survived an earth quake lol, maybe not that bad but it makes my gut jiggle! Smooth before and after 50-60, read up it could be a tire balance issue( driver front one is low) brakes or drivetrain( ujoints seem solid but thats my suspicion)

Jbrew

Plugs should be good enough I guess. Although I consider ignitition integrity important, it would bug me too much leaving that older plug in there.

BTW, - might want to stay away from that Mexican food until it's fixed.

Jefk

chuys for life man lol

Jbrew

What's a chuy ? Anybody ? Sounds like this may be funny lol.

Jefk

you know i could be stranded right now and all you wanna know is whats a chuy, its no body lol, its a heavenly Mexican restaurant chain that dots i-35 i hit up once or twice a week in round rock with buddys

Jbrew

LOL -Well you have a problem with your truck then bring up earthquakes and gut jiggling.

What's anyone here suppose to do if any of those get yuh stranded ?

Jefk

Lmao you made my gut jiggle on that one, i need to make that a sig, i was simply making an analogy of what happens when the truck gets to speed, moms bf finally put in his 2 cents that they hit a curb and might have lost a weight and he aired the low tire up to 38psi while the others are at a stock 32ish, so theres a weight missing possibly and a over filled tire lol
