    UPDATE.......I've now taken the Clubby to a tuning specialist who, after checking ECU codes, undertook the following in order to correct the fluctuating revs that hunt between 500 and 1500 rpm at idle:

    1) The air idle controller and accelerator cable has been adjusted...the cable was reportedly too tight (?).
    2) O2 Sensor replaced
    3) Smoke testing to identify vacuum leaks...none found.
    4) Throttle body cleaned.

    No improvement, so now they're suggesting that as the fuel mix is very lean, and the fuel flow around 25% of normal even after I'd recently replaced the filter, that the car needs a new fuel pump in the first instance, and perhaps an off-car injector service.

    Problem is that once warm, even with the fluctuating idle speed persisting, the car drives beautifully on the tollway at 100kM/h (?).

    So with all of the above considered and after spending $800 on items 1 - 4 above, I'm reluctant to spend even more on the fuel pump and injectors.

    Given the car runs so very well at speeds above 60kM/h, I don't get the mechanic's assessment of it running lean, with reportedly disasterous consequences if left uncorrected.

    I'm now wondering that IF a coolant temp that never exceeds 1/4 on the gauge is accurate, that perhaps too much fuel is being pumped in at idle in order to compensate for what the ECU thinks is a cold engine.

    I'm really clutching at straws now, as I don't want to spend more money for no improvement..............all assistance and opinions greatly appreciated.

    I'm 90% sure I know your issue but I don't want to be that 10% wrong and get buried alive by the armchair experts on here ... take it to Mark and he will sort you out ... #its simple to fix ..

    I forgot to mention that the fuel flow is reportedly 500mL/min.

    The throttle cable needs to have 10-15mm of play, so they are correct there.

    The gauge and ECU have separate sensors. Do you have any problems getting hot temperature out of the internal heater? If so, you could replace the thermostat and see if that helps your problem.

    $800 seems excessive if they have only performed items one to four in your list.

    Thanks PSteel,

    I also thought that the price was excessive and in fact was annoyed, as I gained the clear impression that while they knew what the problem was, they wanted to charge me to work through their pre-determined list of activities @ $120/ hour and charge me double the on-line price for parts such as the O2 sensor before miraculously identifying the "fix".

    After an $800 spend there were still two further items (at least) on their predetermined activity list, being the fuel pump and the injectors, and still no certainty that the erratic idle problem I drove in with would be rectified.

    I don't think that naming the mechanic's business would add-value, but I will be voting with my feet and taking a packed lunch to this forum's endorsed Perfection Injection as soon as I can get some more coin together.

    Still looking for ideas an possible solutions from this Forum though!!

    Tune-Up for VS 5L Manual

    Thats why its good to have a relationship with a tuner. My GTS had a slight tumble took it to my tuner it turned out to be a bad spark plug. Had no errors or signs just a experienced tuner who work the issue and it took only an hour to find.

    When the in-tank fuel pump on my VR stopped , it simply stopped ! I was told by the attending mechanic I would get 3 re-starts by tapping the tank and that would be it.
    He was spot on .
    It has done 260000km on original injectors as far as I know , and runs/idles fine so for a workshop to blame fuel pump or injectors for poor idle doesn't sound right to me....

    Go see Brett and BT Automotive in Ingleburn. He has the gear to tune Delco's has a lot of experience and is a mechanic not just a tuner. He'll sort it out.

    THANKS FOR ALL THE COMMENTS AND ADVICE EVERYONE!

    I thought that I was too old to complain about poor service these days, but after experiencing the lack of service provided by the so-called expert that I took the car to that, as I've outlined, involved them separately diagnosing five individual issues, each of which was claimed as the cause, charging me (excessively in my opinion) to individually correct each with NO resultant fix, then identifying two further possible issues to attend to prior to a further "assessment", and with my car at that time idling and flaring even more than it was when I drove it into their workshop two days earlier, I called a halt to throwing any more money at them with no certainty of a solution.

    They claim to do precision work, but based on my experience it's guesswork.........so I'm not going to cop it!

    The proprietor won't return phone calls, so there's a process whereby dissatisfied consumers can seek redress in NSW, and so if we can't reach an agreement for a partial refund or a no (more) cost fix, I'm now heading down that path!!

    Unfortunately cars do require diagnosis and along the way parts need to be replaced to move forward

    However if they are morons and dont know how to test whats faulty then thats another issue

    Personally i wouldnt bother as you will end up more stressed
