Hey everybody,
I was cruising at about 40 mph the other day in my HDJ81 and I lost all power. The truck would not go over about 15 or 20 mph. Funny thing, although I had no power, it seemed like it was revving much higher than it should. It sounded like around 1500 to 2000 rpm's, though it...
Well mostly, the cruise in my HDJ81 isn't working properly. The light will come on when I turn on the cruise, and then when I engage it it will only engage some of the time. And the few times it does engage, it will only work for so long and then the cruise light will start to blink and it...
I have a 1991 HDJ81 and I'm having cruiser control issues. When I click the cruiser button to engage, the light will turn on. I'll set the cruise at a certain speed and some times it will work, some times it will not. When it does work and the cruise control sets it will only stay set for a...
Thanks for help, mudgudgeon!! Could an old fuel filter or air in the fuel system also be causing me to have poor fuel economy? It seems like I've been getting around 13 mpg. Shouldn't I be getting more like 18 to 25 mpg??
No problem on the questions! It seemed to turn off roughly. I actually wondered if it was starving for fuel, but it had a full tank. And it happened when it was just in park.
Not sure when the last time the fuel filter was changed. It might have been a while ago. I just bought the vehicle...
I have a 1991 HDJ81. When I rev the vehicle between 3000 and 3500 rpm's for maybe 5 seconds or so the vehicle stalls. Does anyone know why this is happening? This was after I had driven the vehicle for over an hour.
Does anyone know why this might be happening?
Thanks!
Thanks for the help!
Do you know if the calipers and rotors are the same at the gasoline 80 series? Or do I need to look specifically for calipers and rotors from the diesel HDJ's?
Just bought a 1991 HDJ81. Killer truck!! The brakes look fine, but when I put it in 4x4 low and first gear, they will barely stop the vehicle.
Any way to beef up the brakes some so that it will stop better or any other suggestions?? Or is this just one powerful 6 cyl turbo diesel??
Any help...
I've heard there a lot of parts that are interchangeable from an HDJ81 to a gasoline 80 series. Is this true? How many different parts? Is the transmission the same?
Just thinking about purchasing an HDJ81. I'll probably have the big end bearings done right away. Other than that, just wanted to see if there was some one in town that really knew what they were doing.
