    Default Engine problems with my 56 plate 1.8 VVT

    Hi Guys,

    Brand spanking new to this forum as I have just become the owner of a 56 plate 1.8 VVT Vectra Elegance.

    Overall I am happy with the car although there seems to be a problem with the engine which I just can't put my finger on - so I thought I would see what suggestions you lovely people have before I take it to a mechanic and cost myself a small fortune .

    Here is the problem, when I am driving along and take pressure off of the accelerator (even the slightest movement) the whole car seems to judder back and forth. This only lasts for around 1 second and isn't very noticable - but I am wondering if it is a sign of worse things to come.

    I would compare the 'juddering' feeling with when you move off in first gear and then take your foot off of the accelerator without changing up a gear - but not as bad.

    This problem is occuring in all gears, but is hardly noticable past 60mph.

    Any suggestions as to what might be causing this?

    Many thanks in advance,

    Tyrone

    Welcome Tyrone, there are more knowledgeable people on here than me, but I would check engine/gearbox mounts first, my 04 vec used to have a bad flat spot/jerk under power, first to seccond, second to third, taking out the bottom trumpet in the air box and a different air filter (fram) and fitting bosch super spark plugs has sorted this, I also used to have a tick over problem and like jerk as I lifted off the gas, regular use of injector cleaner has sorted this but some owners have cleaned the throtle body to good effect, I await other replys with interest. good luck mate.

    I would give the throttle body a good clean out with carb cleaner then a dose of redex injector cleaner as a first remedy.

    Sounds similar to a niggle I've had with our 55 reg Facelift Club for the past 4 years but this has the pre VVT Z18XE engine....Post is below...

    mmm interesting to read about that ECU upgrade.

    I have read about this before on an aussie forum, Appartently their upgrade solved all sorts of issues.
