    My vts has been running pretty shit past few weeks now! when i bought it it wasnt right but now i gotta feeling its worser! Ive changed the coil pack! the map sensor! chucked some injector shit in! sometimes it idles up and down witch could be the idle c valve? ive took the throttle body off cleaned it all out with carb cleaner still the same! I really dont know what it could be! when your driving at like 30mph you let off a bit and like judders by itslef then when you go to put your foot back on the pedal its a late reaction! Pissing me off a treat now.

    could be lambda sensors, if you don't have a clue your best off taking it to a garage coz it could be alot of things really

    Ive had it taken to the garage where i used to work, and code came up so i got it searched and came up with ignition timing or something wittch would probably be the coil pack cus that dosnt come up on the machines. it does pop alot when changing down gear slowly so i got a feeling it could well be lambda sensor/s

    Anyone know? still got the problem! Also... it seems like sluggish i just seen my mate hes got a gti going out of my town goes over a speed bump its a bit wet on the road puts his foot down hit the limeters and went like stink now if this was mine it would not pick speed up that quick! i gotta feeling theres something going on with the air box or something whats not making it go soon as you put your foot down! My engines standard apart from few holes in the air box, decat pipe, backbox, standard mani.

    i changed the coil pack for the running problem still the same the map sensor still the same, chucked some injector cleaner in still the same, next thing im going to do is lambda sensor/s

    Any help why its not picking up speed tho would be great cheers.
