    if the 1.8 is anything like the 1.6 its just below the oil filter

    get the car up on axle stands and get under it - you cant miss it

    unplug the wire, undo the retaining bolt and just yank it out

    took me 5 minutes to do mine on saturday

    try the paperclip test mate to see if any codes are stored in the ECU

    heres the guide: http://www.astraownersclub.com/vb/sh...69&postcount=4
    (ignore the other references in this post as its lifted directly from another thread)

    could be either crankshaft sensor or even the CTS (coolant temp sensor)

    both are fairly cheap and easy to replace - CTS being the easiest as its attached to the thermostat housing

    10 1 10 10

    10 = 0

    so you got
    0335 = crankshaft sensor
    0100 = AFM (air flow meter)

    both components can cause the problems you reported so best off replacing the cheaper item first

    for your X18XE1 engine the replacements parts are referenced under the following part numbers at Vxl

    C/S = 90520856
    AFM = 90530463

    Im assuming you cant get trade club prices therefore the best source would be an independent specialist such as one of those on ebay

    Heres an example of a seller I use all the time

    the AFM is located on the air intake trunking - between air filter box and throttle body - look at pic in ebay link and youll know what i mean
    (2 min job to replace - just make sure u fit it with the arrow facing AWAY from the air box)

    Got to replace the crank sensor first though as its the cheapest and in all honesty the failure of it could be causing a phantom AFM fault.

    as for the crank sensor i cant say for sure but have a look at Matts post above and see if thats any use - my haynes manual isnt at hand at the mo unfortunately

    Maybe grabbing yourself a Haynes manual would be a good start.
