    Ensuring a smooth running z20let

    Just thought this could be a good idea, as there seems to be a fair few things that can be kept ontop of to ensure that the z20let runs as smoothly as possible, including things that need replacing/checking apart form obvious checks such as oil/water and the like.

    So what do you think should be checked/changed on a z20let to ensure its running at its best.

    a few things people have menitoned:

    AFM
    Boost control Solenoids

    so,theres obviously more, so what have you changed thats made a difference?

    lambda's and fuel filter are a common cause of cars not running true and most people shrug them off!

    i dont mean it needs changing every service but its always worth changing after about 30 to 40k in my opinion

    easy, too clips either side, don't even need to jack the car up to get to it. Just depressurise you fuel lines by twisting the nozzle on your fuel rail, then de clip it, get it facing the right way for flow and reclip back in, retighten fuel rail. Job done.
