So, thanks in advance for any assistance here. Have a bit of an issue, as follows:
1994 Dakota 4wd, 3.9, auto trans.
Bought this truck 5 months ago with 94000 miles on it. Ran great. Started great. Good mileage, around 18 ish.
Every once in awhile when I started it, it would buck and misfire for a bit until it warmed up good. Seemed like if I ran it for a few minutes, shut it off, and then started it up it would run good again.
Then I noticed that when I hit around 150 or so miles on a tank, it would run out of gas? If I added gas, it would run good again. Once it would hit around 150 miles it would buck and stumble just like it was out of fuel. I always carry a can of fuel with me, and if I would pull over and add a couple of gallons in it, it would smooth right out and run fine.
It seems like the problem is getting worse. Nearly every time I drive this, it seems to take longer and longer before the engine smooths out. At first, it took around 9-10 miles on the highway and it smoothed out. The last time I drove it, I went almost 70 miles and it was still slightly missing when I shut it off.
I put new, plugs, cap, rotor, and wires on it. Changed the oil and filter. I noticed that when I pull a trailer, that the engine runs pretty hot too. There is no oil in the antifreeze, and no antifreeze in the oil. Doesn't use oil. Doesn't smoke any. Doesn't use antifreeze. No leaks of any kind on the truck. No engine lights come on.
Not sure which way to turn with this. I have another parts truck that ran good. I thought that maybe I would take the gas tank from the parts truck and put it on this one, but they are both have skid plates under the tanks and look like they would be a pain to change.
Any advice would be most welcome! Thanks again.
