    Cool Revs holding between gear changes

    Any ideas please, Astra 1.8sri, 2008, when driving in any conditions (traffic, main roads etc) when i change up the gearbox the revs hold for about 2 to 3 seconds, on the odd occasion the car works as it should between changes, the car has done 28000 mls, any input would be great.

    Thanks...............

    HMMM....

    Id say it may be the ECU...it may need replacing or re-mapping....but dont quote me.

    The ECU will control all the input of fuel air etc so if its revving like that maybe it needs a prod in the brain..have u tried unhooking the battery for 24 hours and trying again ( make sure you have radio code and are able to get in the car when its unhooked to open the bonnet)

    sorry i cant help so much?...

    as the thortle on most astras are fly-by-wire and not cable, it tends to rev ever so slightly longer than you depress the peddle.

    its a very normal thing to happen, its just the time taken for the signal to say that you have taken your foot off takes to reach the engine.

    Thanks for the info, does make sense, but annoying, looks like i will have to live with it for a while as i have only just bought the car a couple of weeks ago.

    Thanks again.........

    when i first got my astra it took me a while to get used to the fly by wire system.iv taught myself to lift off the throttle ever so slightly before i engage the clutch, seems to time the gear changes a bit better.

    hi, im getting this to my astra sport 1.8 16v. but my throttle body also has a cable as if it is a accelartor cable. surly there must be somthing you can do instead of lifting of the pedal 2-3 secs b4 a gear change, evan then it dosnt sound or feel like a normal gear change.
