R33 Gtst Cuts Off?

[tehbebe]

My car is having issues where sometimes the rev's would just fluctuate by itself and then eventually just cut off (while driving or on idle). I would try to start it up again and it would crank the first 2 times, then eventually nothing would happen when you turn the key (no click, no sound at all).

To get it running again i'd have to get it jump started, then it would run fine.

It's died 3 times already, the past 2 times have been when i've just been on idle but one time it just completely turned off while in the middle of driving.

What could be the problem? any suggestions?

thanks

have you cleaned your aac valve and afm?

i took out my afm and checked it, seems clean, but i changed it and put my friends r34 gtt afm in just to try it out anyway...

and uhh.. aac valve..? lol

[ClutchBurndout-:(]

heh

its most likely your aac valve if it has never been cleaned

just remembered as well, when i turned the A/C on (While i was idling), the revs would start fluctuating, would that still be the AAC valve?

and thanks for the link ill check it out

i had a stuffed air con compressor and when the car was idling the revs would continuously hunt up and down from 1000 to 500 with the air con on. Air con off it was totally fine. Scrapped the air con compressor, bought a second hand one and runs like a dream now.

This fixed my problem, but sounds like yours cutting out might be more than just this.

my idling is fine now, no problem in fluctuation in revs, but brings me to another problem, after my car has been driven hard, or given instant high revs, or pretty much when it starts to get warm, it just dies on me. If i go to start it back up, it just clicks, it wont start up on me again, eventually if you keep trying to start it up it will eventually die and you wont be able to start it up again unless i get jump leads... but here's the thing, if you pop the hood, let it cool down for about 20 minutes, it'll start up again no problem.

ANY ideas?

check your fuel pump when it gets got it could stop running properly. but id be looking more 2 wards tps or afm. what afm are you using? did you do a computer reset when you put it in?

[Muff]

if it just clicks it usually means your starter is stuffed. not sure y it wove stop your car tho. does it try and turn ova when you turn the key or does it just tick. sorry bout the last post didn't read yours properly.

[tehbebe]

it still clicks when it dies out but eventually if you keep cranking it, it won't even click at all.. although if i let it cool down on the spot without trying to start it up, eventually it'll start again fine. it only seems to just die on me in hot weather or once ive really 'driven' it.

Check simple things like your battery, your earth etc.

Could be a dodgy earth somewhere. Heat creates more resistance

Or could be a couple issues, check cas and afm (check the wiring to the plug as well)

Sounds a bit like an earth problem as the symptoms come and go and affect hot-starting and make it cut out.

Could also be your alternator... Got a volts gauge or one you can hook up? If your getting a flat battery while driving (which seems to be what your describing), it'll cause these symptoms...

it definitely sounds like a battery/alternator issue to me as well. this doesnt mean that either are stuffed, you just need to check your terminals properly.

first thing i'd try is a separate earth from the alternator housing to the chassis and see where that gets you. try use a thick earth wire for this. then try the earth on the battery. if thats no good then get someone who knows how to use a multimeter to test your alternator and battery.

You'll need to check them while the car is breaking down/driving/under load though, as if it sits and idles ok most of the time then testing the alternator then might not tell you anything...

thanks guys, for the updates... the battery and starter/alternator is one of the first things i checked out aswell since thats what i thought it was in the beginning, some guy checked them with some stick thingy lol and said they were fine and it was "charging properly" then he was like "i dont know much about jap cars, take it to some jap place" so i was like okay cool..... lol

i changed my AFM, cleaned AAC, changed fuel pump and fuel filter.. now i was hitting constant boost while driving home one day and it cut out again, this time cos i was on a main road and by myself i just left hazards on while waiting for a lift to help me out cos usually like i said, if i let it cool down for a good 20 mins - sometimes an hour i can start it up again.. but this time it just completely died on me, so the hazard lights eventually let my car to die, some random came and jump started me and i was able to get home fine.

i can drive the car fine, as long as i dont hit constant boost other wise it will cut out. im gonna try look into buying another alternator and see how that goes, if all else fails, ill try a new battery, umm im gonna also unblock my BOV and just put a proper gasket with a hole in it instead of the plate i have. just a thought.

try adding an extra earth cable from your alternator to your chassis.

hm okay ill look into that and get back to you XD
