cleaned throttle body,
cleaned the idle contral,
new map sensor,
new plugs,
new ht leads,
new cap n cog,

+ nothing comes up on vag come for errors*

hmm im lost for words 

[trog_nfs]

is it all the time or when hot/cold?

Could be temperature sensor or a vacuum leak

[mani12354]

hot and cold lol, thing is it i checked every hose and there was nothing leaking no rips or tears there practially new

Ignition coil is quite common to fail

[mani12354]

true but would that cause it to jerk backwords n forwards at 3.000 rpm

[tweed]

My sister had a ibiza ABF and the coil went a lot on that, but often wouldn't start at all 

[Sii]

Please don't be offended by this but is it posible when it had the new plug leads they were put on the wrong plugs?

Just a thought.....

Unlikely, it would be running as rough as a badger!

not all coil failurers manifest in the same way. Coil would be my next port of call given what you've already checked and changed

[mani12354]

LOL its running like a chainsaw now :O

Have you not changed the ECU relay?  Mine was rough as and that was it.
