*help* My car IS screwed..funny..

[[[d a n n y]]]

ok guyz..i got a problem..a serious problem...

i was wondering if u guyz can help me?

ok i bought my GTR on tuesday

i had to jump start it cuz it hasnt been driven for 2 weeks.

once i jumpstarted it ,i was on my way home.

around liverpool about 30mins into my journey home....

the car just shut it self off in the middle of the road..

making my GTR look like a POS

anyway...i manged to push it off to the side of the road and bought new batteries..and replcaed it on the road...the car fired up after the replacement battery...i gave it a bit of rev..

it'll rev till 5K and then stop..once i drop the revs the car will shut it self again...

only this time i can start the car over and over again.

i managed to get it through the busy sydney traffic and to my mechaics place..

today after 2 days i've bought it...the AFM's once though were at fault were not at fault nor the ECU

now i am really running out of ideas...

i was wondering if any1 could help me..

currently the car is running super rich blowing balck smoke like a chimney

and refuses to rev past 3g the car it self has done less than 500 KM's since brought in.

does it have spark plugs in it ??, running rich, doesn't like load or high revs, anything ignition related would be my guess.

spakrplugs have breen replaced..

funny thing is..

it just happend.while i was driving..

[meshmesh]

Didn't you get the car checked out before you bought it?

Danny, do a search, If I remember correctly, there was recently a thread about the car switching off all the time..

[[[d a n n y]]]

YES SIR..even though that might help..

i really dunt know what to do..as the GTR is my first turbo car

and i dont know what to do..

put it in the scanner too..and the scanner says all systems ok.

so i was like wtf?

danny i think its the throttle body being dirty...

u got new batteries and also got spart plugs replaced

which means the throttle body is dirty..

u can clean the trottle urself.... only need a tooth brush and some trottle body cleaner

and it shouldnt do it again... if it does then i dont hab a clue

unless u got the wrong batteries

How did you find out the AFM is alright? Did you replace both with a working unit?

How about switching the little silver box at the back of the plugs (Ignitor I think).

I would first put the ecu into diagnostic mode and see if you get any error codes.

But my guess would be the o2 sensors being that is running so so rich.

I believe Danny has since had a full engine rebuild, so would be interesting to hear an update

First things first your car only has one battery. There is no way that it will be your throttle bodies (yes you have 6) the rb26 has a multi throttle body setup to enhance throttle response. Throttle bodies being dirty wouldn't be an issue. In extreme cases they mite hamper performance if the airflow is being restricted, but in no way could they cut the engine completely. The chance of it being an o2 sensor problem is also slim as they only trim the mixture. id more inclined to check for air leaks after the afm's in all the intake plumbing that would make it run rich but i doubt it would completely cut out. It depends on how much has been modified on the car too. Like sumone said it could be the ECU especially if its an aftermarket unit playing up. Best thing to do is take it to a fuel system expert.

check to see if the ecu is fully plugged in ... or maybe get an ecu that is fully working ... maybe the ecu isn't fully contacting the plug somewhere ... i've seen this happen before ... on a normal gtst though
