Pajero Vibration

Is it a petrol or a Diesel Makes a hell of a difference in the replies you will get.

More info = better answers

Thanks very much - It is a petrol vehicle.

Check the engine mounts.

Check the Transmission mount I believe it has some sort of harmonic counter balance on it.

Plugs or leads could be stuffed and breaking down under load.

Had a car once that did that and got out one night and looked under bonnet.
Was a fireworks display as plug leads were shorting onto a heater hose fitting coming out of the block.

Possible electrics breaking down under load but if not, get trannie checked.

check fan blades on cooling fan,

Thanks to everybody who assisted and gave suggestions it was very much appreciated and reflects what a great community you are. As it turned out it was an electricals issue. #6 cylinder was not functioning due to a cracked spark plug and lead arcing out. The prob was exacerbated by an oil leak from the cover gasket. HT leads were replaced etc.

Thanks again.
