hi there just brought a mk4 golf 1.4 and its strange because it starts fine but then runs for a bit all good then turn it off and turn it on and idles a bit lumpy as in nearly stalls but never does then rev it up to about 2000 for a bit qand then its fine again anyone no the prob ill prob do a service on it could it be a fuel filter slightly blocked or something? cheers

Clean throttle body

ok on these are they self adjusting when you put them back on just start up and leave to idle? and will reset its self? cheers

If its a cable operated TB, then it will reset itself after about 100 miles, if its the other (electronic TB) then I think you  need to re-align it with Vag-com.

and before you ask, you need the full version of vag-com (vcds) to be able to re-align

my 1.4 did the exact same thing when i stopped at traffic lights the revs would drop them jump up then drop so low it would cut out, paid £10 for garage to clean throttle body and it never did it again, you can do this yourself theres a guide on how to do it on here but for £10 i just got garage to do it. that would be first thing id advise you to try
