    Hey guys!

    I got some weird issues with my Z starting it up today. Here are the
    problems I've noticed (Car is an Auto NA)

    After car is warmed up

    -Park Mode car is at 2,200RPM
    -Idle Mode car idles at 1,200RPM
    -2nd Gear always struggles to change to 3rd
    -Very rough when gear changes sometimes takes ages to change
    -"Power" light flashes when I start up the car, just noticed it.

    Anyone know what the issue is? And what options I have to fix it?

    Does it hold gears for ages before shifting? Im having similar problems, I ran the auto diagnostic and it showed all clear, but my auto fluid is black and chunky now, is yours still red? Heres the diagnostic:
    2'nd time I've stolen that in two days lol.

    Yeah but only when reaching 3rd gear. auto fluid is dark red.
    My overdrive is disconnected lol gonna have to put it back in to perform
    this test!

    Gonna check to see if it still does the same thing...

    Okay,

    Park Mode = 1,000RPM
    Idle Mode = 900RPM

    Things seem normal that's odd lol gonna take it for a drive see how it goes.
    "Power" light still flashes when starting up the car and neither Power or Hold
    mode is on.

    Power Light stopped flashing, idles are perfect and the gears
    are changing great and smoothly! Z's are a weird car lol
    Guess things are okay.. will still keep an eye on it.

    If its something that comes and goes, it will usually be an electrical gremlin somewhere... Could be loose connectors, shorting wires, fubar sensors etc.

    BigCol That's what she said...

    Could also be a faulty TPS. Seen them do some wierd stuff before. Check the voltage setting, and make sure the connections are clean & tight.

    I would put money on this being the problem.

    Mine was doing this when I first got it.

    TPS just needed ajusting
    Now changes like a normal car.

    My flashes are as follows;

    1 long, 2 short, 1 longish (but not as long as before), then 6 short, and 1 long

    Can someone tell me whether or not I count the 1 long flash in between the short flashes as just a short flash, or am I getting 2 different error codes??

    Sorry if this is obvious, but I want to make sure :zlove:
