Lads would appreciate some advice.My 00 b4 is suffering from a severe hesitation and jumpiness at 2000rpm.It feels similar to when I had a break in ignition lead on previous car but it is only in or around 2000rpm.it is making me very paranoid driving it but its my only mode of transport.would this be the maf sensor??

Do both turbo's spool simultaneously on the B4's or is it 2 stage?

2 stage, primary turbo spools to about 4,200 and then they go to parallel turbos with both working together
 
plugs or coil packs I'd say. Mine is doing it too at around 2000RPM.
 
Take it out the motorway and up above 140kph see if you get a cel-its what mine does if o2 sensor is gettin dicky.
 
new ngk plugs went in it last week (pfrf6b platinum) ,had it on motorway yesterday no CEL but sometimes felt a bit sluggish.Any info on coil packs and o2 sensor appreciated lads
