    Bad throttle response...

    Morning all,

    Over the past two months my throttle response has slowly become worse and worse, to the point now of me getting really fed up of it being so sluggish. I've cleaned out my throttle body so much so that it's almost reflective, and have a derestricted airbox with green BMC filter and a modified cold air intake pipe, similar to the size of a Veccy C pipe. I think I may have a small hole in the exhaust, would this affect the throttle response this much? I have to put my foot down for like 4 seconds to get it to rev limit, and it never used to take that long.

    Would other suggestions would you have for bringing it back to normal? It's a Z18XE by the way, in a 2003 hatch.

    Thanks!

    Sam.

    Might just need a sevice( Plug change)
    Is it misfiring? (Plugs/faulty Coil Pack)
    Is the clutch slipping?
    Could be a Faulty Air flow metre?
    Is the handbrake on (only joking)

    It is due a major service in the next couple of weeks, so that could help... It's not misfiring and the clutch isn't slipping. How will I know if the AFM is faulty? Is it just a case of replacing it and seeing if it solves the problem?

    Thanks for the help,

    Sam.
