you need to reset the ECU do this by disconnecting the battery for about 2 hours. reconnect the battery and start the car DO NOT touch the throttle for a few mins let it sort itself out it will cough and splutter but thats normal all it is, is the ECU resetting itself hope this helps

is it misfiring or just spluttering after you restart it?
it does this first after you reset the ECU as its trying to recalibrate itself

misfire would have nothing to do with air filter????
gotta be spark plugs or leads.... prob just need plugs replaced.

it was misfiring had it serviced 3 weeks ago the guy fitted new spark plugs jus been havin a looky and literally they were not even tight jus had the torque wrench to them tightened them up
he replaced one of the leads which cost me 30 quid for 1 lead jus went to pull it out and it broke its old and shit!!!!!
went down to halfords got a set of high performance leads for 35 quid
may aswell serviced myself would have saved 150 quid

i can't understand re calibrating by resetting the ecu, the sensors would adjust automatically without all that  sounds like a waste of time
misfiring won't b filter,
