After all the work to find where the vacume pipes go and to finish the rebuild of the passenger side head and replacement piston ,the car now starts fine and ticks over very smooth,when i drove it on the road 30-40 mph with gentle throttle it cut out like was starved of fuel it then perked up and ran fine for about 15 miles,i took it for an mot yesterday and it passed with no problems,i collected it from the mot station thismorning and felt confident to give it some throttle but the car felt very held back and didnt boost ,the revs semed to stop at 5 and there was no power,it then started cutting out in a on off way but it did not stall,then it settled down and ran fine for a mile or so,then it done it again when i was doing only 15mph,,i have got to the point where i just dont know weather to sell it as it is or find someone to fix it,i cant take it to Z-WORLD as its nt taxed and its expensive to get it transported over to them..ANY IDES WELCOME.

Would start with boost leak test and make sure nothing is lose connectors etc, could also be afm and a million other things

i have a friend who will plug it into his computer for me and later i am posting a video of the symtoms and the general condition of the car as i might get lucky and find someone who wants the headache of it :)
