never rains but pours as they say.  Sorted the miss fire it was one of the hoses on efi had a split but couldn't see it without taking off.
But now i have alot of vibration under load any gear not there if free wheeling. Front diff has recently been changed.

Just from taking the injection system off? something has not gone together correctly, the any gear is a clue that it's engine related.  Double check all you connections, injectors etc and that the leads are all secure, in the right place etc.  You need to have the EXACT routing shown in the manual too.

Is it the flapper EFi, I'm wondering which hose was split and what you could have disturbed putting it all back.
