After the faf of emisions light 2 months ago(relaced dis pack), yet more probs.
My service was due, so i got spark plugs(2 prong type, wheres the ones i removed had 4) + fuel filter. All was fine till i took it into master fit for oil change and 41 inspection etc. Problem is now just a few days after the service when i take my foot of the throttle the car kinda 'hops' mis fires type thing as it slows down(clutch still engaged). its done it twice now and its quite severe. Any ideas?
