    Default Z30DT staying on place, but RPMs jump

    Hello guys!
    Today I saw interesting thing on my Z30DT- when engine is hot you put on neutral or stay at red light (A/T gearbox) and in tachometer see that rpms are little moving (can be heard as engine works different)! Similar problem was before I replaced SCVs, abowe 3 months before! Maybe is caused by minuses which are today outside or caused with charging load- as now its mirors and rear window heating, blower etc?
    When SCV was damanged engine stopped, now its only little swinging????
    Thanks for Yours oppinion!

    My Y30DT also exhibits this (the revs on idle have slight movement)
    I first noticed it when I had the car about 18 months and reported it twice
    The dealership couldn't find anything obvious
    On the second visit the Area Technician agreed it had noticeable slight movement
    He advised me the next time he saw me that it was a known issue and reports were increasing, however there was no known solution
    He also rechecked it on conclusion of the SCV problem two years later
    He did note the higher cycle was on a specific position of the cambelt but no other fault could be found

    I've just put it down as a design flaw and unless you actually look at the rev needle close up you won't notice it
