    I bet 10 bob that if you disconnect the EGR plug and drive it that your lag and jerkyness goes. Mine did on my 120.

    i have just had this jurky problem, i renewed the injector rubber leak off pipe (£45 new from vx) and injector cleaner in full tank of fuel, worked a treat.. i have also cleaned egr valve, boost sensor, throttle body, maf sensor, renewed vacuum pipes, give it a full service and the problem was still there after all this.

    Snap, iv cleaned my egr valve, maf sensor and the little boost valve held on with 1 torx bit, all thats made a massive difference to the speed and acceleration but im still gettin a bit of lag and the jerkyness, iv been told about a 3rd injector could be the problem but i dont know, its pretty frustrating because its intermittent and its deffinatly going to happen a couple of times on every journey i do and i cant seem to solve the issue
