hiya is it possible anyone can give me any advice?? just had a 2l zvh build and is now in my mk3 cabby, having starting problems all the time with it, and when it does start it seems very slow to pick the revs up and when hitting about 5000 revs u back off and the meatering head flap chatters ? is this loss of fuel presser or something along them lines ?? any one had this problem b4 ??

thanks guys
