    no it wont effect anything, just make sure when you crush the old one off with pliers that you get all the old bits off, including the small chunk that is stuck in the slot on the shaft. you'll see what i mean anyway. what it is from factory 16v rotor arms are glued on, but ive never bothered gluing on replacement ones

    basically get some mole grips or pliers, then gently clamp them round the rotor arm. after a bit of pressure you should hear a crunch, then you can pull all the bits of rotor arm off no problem. there is a groove in the end of the shaft which locks the rotor arm in place so it cant spin freely, there will be a chunk stuck in there. use a screwdriver to pick the bits out :)

    if its glued on yes, it may be that someone has already replaced it and it just comes right off :)

    ah, by rubjonny's post I thought that the rotor arm needed to be cracked with some pliers

    it will need to be cracked off if glued on, which they are from new. but if it was replaced probably it will pop right off :)

    one thing to note is the as stock the KR should run super unleased 98 ron, so if you have put in the cheapo 91 rom you get in europe then it will run like pap, so that could be part of the problem

    right,

    I just got myself:

    -distributor cap
    -rotor arm
    -4xspark plugs


    I'll replace all of these this afternoon. I'll come back at night with news.



    In case it doesn't fix the loss of power, I'll try using the old set of spark plug leads which was working fine when I replaced them.


    I've also bought a fuel filter in case all of the above fail.


    If, then, the car is still running wrong....... I'll replace the whole engine with a freshly rebuilt ABF as I've been wanting to do it for a while and now that I've found a better job... it looks like it's the time!

    hi there. I replaced the dizzy rotor arm+cap+spark plugs+leads and the car is still very down on power...

    I've only left to test the worn crank pulley or something that I've been suggested here (I'll do it tomorrow), and a compression test...


    does anyone know any ebay seller that sells compression testing gauges??

    thanks....

    Today I

    -added a wire from battery negative to head
    -did some autodata - ignition tests, and the ECU is okay
    -hall sender plug gets +11v with ignition on. Autodata says it's okay if voltage isn't lower than 5v.
    -checked vacuum pipes, no leaks
    -checked air filter, no oil/dirt
    -checked oil recirculation pipe, not blocked


    I'll take it for a drive and post the results.


    I bought myself a compression tester gauge off ebay. Should arrive by 7-9 days. Place your bids !!


    BTW:
    mpg "used to be" about 28mpg when the car was running fine
    now, it's 23mpg!!!!!

    well the car is still running like a 80hp non-turbo diesel after what I did on the 27th of Jan...

    What annoys me is that, even in neutral, if I accelerate (pedal to the metal), revs go up really slow...

    now I need to shift down to 4th on motorway if I want the car to accelerate, while I could do it in 5th before :S


    I know that a compression test (the gauge is on its way home) will tell if the engine is OK or not but I'm stuck at using the car like this as it's my daily....


    I've thought that the in-tank fuel pump's filter (the basket one, I think there's one?) could be blocked. is that hard to inspect? Will a vaporised fuel party be with me while I do it??


    thanks for reading :)

    does the throttle flap open fully when the throttle pedal is fully down to the floor? is the retaining clip on the plastic part of the cable near the throttle body
