    Symptoms of a failing egr?

    Hey guys can anyone tell me the above?

    I have recently bought a new lambda, cleaned the throttle body, bought a new maf sensor and given the car a good service but yet when I'm in say 4th at 40 and decelerating, the car gets a case of kangaroo petrol and starts jolting

    It pulls away smooth enough although every now and again it jerks quite bad but is then fine and the only reason I can think that it's doing this is because of the egr

    Am I on the right line or could it possibly be something else? Cheers guys

    Dealers actually blank these on the X18XE1 now im assuming thats your motor as the Z18 dont have an EGR.

    Had similar symtoms myself not bad but they have gone away since i blanked the valve

    ive got an egr blank sat next to me but really dont fancy that route, i would preffer a long term fix as blanking the egr will cause a few problems in the long run

    Hmm what problems? im pritty sure VX wouldnt blank them if it did cause problems

    TBH i think its weird that they do blank them when they could charge you for a new EGR valve, there must be a reason why.

    On mine another thing I've found that has improved things is to take the slack out of the throttle cable.

    before it wouldn't start opening the butterfly valve until the pedal was pressed a little bit more. not talking loads just a little bit.

    Yea I've already removed the slack, throttle response is so much better, and I've read a few posts on here stating that blanking the egr should only be used as a temporary fix. The z18xe doesnt have an egr as standard but the x18xe1 (which mine is) does, I did blank it off once before but was only till I got a new egr, but again I don't want to blank it off it it's not the problem, this is why I want to see what the symptoms of a faulty unit are
