basically im gonna try best describe what the car does.
sometimes the car will drive fine for half a day or all day then all of a sudden the car will start surging just while driving along at 60kmph or 100kmph
this is when the fun begins, once the car starts surging it will basically just cut the ignition and u have to put ur foot flat to the floor to keep the engine going, thing is the car doesnt rev or go anywhere with it flat
to the floor, u can hear the turbo spooling and the bov goes off a bit but the motor isnt reving or accelerating and thats flat to the floor for about 20-30secs, and if u take ur foot off the accelerator the car will die
and u have to roll over side of the road and kick it over 3-4 times before it will go again.
the fella has a powerfc there aswell that he has tried plugging in and using on base map but it does the exact same thing.
does anyone have any ideas? we r out of ideas.
have tried replacing the above items but nothing has fixed it.
