    Advice on hesitating Astra

    Dear Astra-sport people,
    My car has sometimes hesitated when pulling off especially when i`m doing so in 2nd gear or trying to pull away quickly. Its a mk3 94 Astra GSi 2ltr 16v redtop engine.Is it something to do with either the injectors or fuel pump i.e fuel trying to get through but can`t do so at the rate that is needed so they may need cleaning? just a thought, if not then any advice or suggestions would be great. Also my engine was recently diagnosed as having a sticky hydrolic lifter on one of the valves which is particulaly noisy when cold, has anyone else had experiance of this if so how much did it cost to get sorted? When i took it to my local vauxhall dealer they suggested flushing the engine 1st to see if it cleared it which i did but has`nt done so !!
    Cheers.

    Does the engine management light briefly flash when the judder occurs?
    If it does (as mine did when I had a similar problem) it makes things a lot easier to diagnose! Mine turned out to be a faulty crank shaft sensor.

    Do you use fully synthetic oil on the red top? might be worth down grading to vxl semi-syn, still a safe oil to put in and cheaper.

    You might have a slight fuel or air leak causing the hesitating.
    Cant Think of Anything Funny To Say
