If the fuel wasn't getting to the engine, you'd have misfires and a code more than likely. What rpm you at when you get to 120. Do you keep rising in rpm but not kmh. Trying to get a feel if maybe tune up or something

So, I was doing some super light 4wheeling, mostly just tearing around a cranberry bog last night and when I got home I noticed a slight vibration that seemed to shake the door panels (almost like the speakers do, but there was no music playing). Its not a catastrophic vibration like the death wobble (I now from personal experience), but its bothering me to know what it is. Its worse when I'm parked or in reverse. Any help would be great!!
Second note, only supper rough part was when I misjudged a puddle depth-wise, and slammed out of it. Potential cause?

That's personal preference, I suppose, but if you engage 4 wheel drive, with a different diameter tire in front and back, you could run into some issues.

Ok new question, i know calibers from 90-00 are all the same. But what about brake pads, my issue being that I don't have the right brake pads. And I don't know the year of my Dana 30.

How does it perform at lower gears? I would imagine if you injection pump had a problem you'd be able to see it at a specific RPM or just under load. Stomping on the pedal should be similar, what about climbing a hill in 3rd?

Lad doesn't have a gasser lol. Accelerator pedal controls fuel how much fuel is injected.

Yea and I remember later about diesels and fuel is injected differently than gas engines. Also why tuning a diesel pickup works easier. Less chance of early combustion an explosion in the engine
