hi i have recently got my hands on a mint condition 2.9xr 4x4 , if i drive car straight away after starting her she hickups badly, but if i leave it ticking over for a few minutes its fine, also occassionaly owt on the road it feels like it dies for a split second and then is fine again.
i changed the plugs the other week with no success, any help would be much obliged
