then its started playin up... pulled off from the lights an it cut out...started agen pulled off an started judderein

if you pull off nice an slow its ok but you exellerate abit its started judderin an it wont stop

its does it thru every gear

but if your not in gear you can rev the bolox off it an its sweet

i went to work an left the car at home an my dad had a look and there was nothing wrong with it

he took it out an it was runnin sweet

im reali stumped

Dirty fuel? Blocked vacuum pipe that got unblocked eventually?

It it ain't still happening, don't worry

i had this a month back, and it was cos it was running very rich. Get the emmisions tested, and tune to factory spec.

wel i thought it was sh!t fuel cuz ive always had problem with bp fuel...it messed up my old car

i had a petol leak on the injector rail so i think there might be sum trapped air in there knockin about

could it be that?

8v digi?

Ah right, refer to the RJ tune up guide and check all earth connections. Then check the fuel pump.
Does the fuel pump prime (hear it?) when you turn the ignition to 2?

^^ if that checks out, pull the electrical plug off the main pump under the car and repeat the test.  if you dont hear the in-tank pump prime that would be the problem!
but fix the fuel rail leak before you do anything else, often the ends get all cracked.  just chop a cm or so off the line and refit

ye its a 1.8 8v gti...thinks its a digi?

wel its not doin its any more

i can hear the fuel pump prime its all sounds ok

i think it was sh!t fuel but il run some injector cleaner through it just to be on the safe side

thanks for your help
