Intermittent running problem with 1.4 Corsa

    I've got an S-reg Corsa with a 1.4 litre 8 valve (HiTorq) engine, which
    has had an intermittent engine fault for most of the year that I've
    owned it.

    The problem is a sudden momentary loss of power, which causes the car to
    judder. I have been able to demonstrate this problem to my local
    Vauxhall dealer, who diagnosed it as an EGR fault, and replaced the EGR
    valve. Unfortunately, this has had no effect. The garage have run a
    Tech2 check on the car, which did not reveal any further information.

    This problem seems to be related to the amount of petrol in the tank.
    It is at its worst when I have just refueled, and gradually diminishes
    until the tank is about three quarters full, after which it hardly ever
    occurs. It is also effected by petrol quality; I usually use Shell
    Optimax, with which the problem is merely annoying, but with Tesco
    unleaded the sudden loss of power is sometimes large enough to be

    Can anyone suggest a solution, or recommend another garage in the
    Maldon, Essex area that I should take it to?

    Thanks in advance,

    Thanks, I'll take a look at the weekend. Up until now, I've always relied
    on the garage for this sort of thing. How difficult will it be to do
    this for myself?
