hey guys,

tonight i was driving down the freeway in 3rd and noticed as soon as i put the foot down to change to 4th gear my engine light flashed and then didnt come on again.... i have a stock r34 only mod is a catbak zorst, wat does it mean when the engine light comes on? the car felt normal though it didnt sound like it was missfiring or boost cutting... any help will be appreciated thanks

would it be an o2 sensor ?

Your ECU has logged a fault.

where can i get this fault fixed? nissan dealer im from melbourne...

[shif_tea]

you can check the ecu to see what the fault was. I'm not sure how its done with r34s but someone else might know. Might be the same as for r33's, if so, search it cause its been posted a few times. If you take it to nissan they can check it with datalogic and see whats the problem. Could be nothing...

Its gonna be one of your coil packs for sure, common problem

Search aaround for the diagnostic procedure and this will confirm it

i found the dignostic test procedure but it says only for nissans 1988-1994.... :S ill try it tommoz is the ecu on an r34 the same as an r33 near the passenger side?

Hello,

More than likely it is O2 sensor, this happend to me once.

But do a check.

The mechanic at the time bridged some point up with a wire and the dash lit up several times to

notify us of the fault and which sensor it was.

I am not sure if this is the same for R34's.

im doing the procedure right this moment.... so ill let u know wat it could be..... scared lol

i think i need to take it for a tune?

congrats on finding a PFC where your standard ecu should be .

Yep, get a touch up tune just to make sure everything is ok.

With a PFC the check engine light generally flashes if the knock reads >60. I'm guessing it knocked a little when you floored it and put the engine under load a little. Just get a touch up dyno tune done .

thanks im so excited thats saved me heaps of money lol

Man.. nice find..

I had this problem when I first picked up my r34 turbo from the dealer.

He did the diagnostic and it turns out it was a speed controller. He said just keep driving it till the part comes in... Then 3 weeks later the warning light switched off and no problem since... Though I have had the speed controller replaced just in case but it is amazing what sorts of warnings this advanced electronic controlled cars can give you.

Battery was out of the car for one week whilst a body kit was installed, then the driving to work on the F3 in Sydney to Gosford car turns off and does some sort of emergency breaking, turns out one of the battery cells had died and was only causing a fault occassionally when more then normal power was being consumed. Naturally this was a wet day, so had headlights, wipers, stereo and the driving aids were occassionally kicking in.

Anyway, moral of the long and pointless post

Find yourself a good "import shop" that you can build a relationship with so that you can have problems solved easily and without being ripped off or car damaged by a mechanic who does not work with imports.

Also just incase you didn't know where your diagnostic plug is, it is below the steering wheel to the right it has a little latch where you can unplug it and then plug it in to a diagnostic tool or workshop... or even one of these great new toys from greddy I seen in the latest high performance import magazine.
