Outer Limits 4x4 Board

I am new to Pajero's but have just recently bought a 1991 NH GLS 3.0L V6. It is is very good condition. However The engine seems to be running a little rough. It seems to be missing on cylinder 6.

To give the best description of what is going wrong i have uploaded 3 videos onto the following site.

Any help would be greatly appreciated.

yeah i just bought a 92 nh 3.0ltr and its doing the same thing just wondering did u fix it or are you still pulling your hair out lol

I could'nt get your videos to work. What tests have you done? How do you know it is cylinder 6? Have you checked spark? Injector pulse? Compression?

i finally got to having a look at mine and it was the dizzy cap and the firing order was not right. the only problem i have now is it has a flat spot from idle and a slight miss but it goes away at about 1500rpm any ideas

start with the simple stuff. Compression check,at that age I wouldnt be surprises if burnt valves. Not a majorand valve stem seals can be replaced at same time.Go out at night when dark and look for spark jumping from leads, this be encouraged buy squirting with water from old kitchen pump cleaner bottle.They are a good old simple donkbut are worked hard pulling around those heavy nh bodies.

I have fixed the video's so they should be working now.

In addition i have noticed that the problem gets better as the engine get hotter.
