when i first take off in my ef xr6 it surges about mid throttle and will do it in about the same spot each time i take off for about 1km then its fine. the more i drive it the better it gets but when i turn it off and leave it for more than half an hour it does it again..............................

Have you changed the fuel filter....put some injector cleaner in it, checked the HT leads, checked the spark plugs, checked the tightness of the inlet manifold bolts???????

Iv tried new fuel filter, plugs, leads, different injectors. I was reading the it might be the PCV valve. Something about it can lean out cylinder 3 and 4 if the valve is blocked.

On the dyno my car leans out at that surge and when they put there foot down a little bit more it goes back to normal a/f
