R33 Turning Off

[rutelz]

Hi Guys,

Just wondering if anyone else has heard of or had the problem where your car shuts itself off during driving?

Its does it in warmer weather or after giving it a thrashing?

Any help would be good because no Auto Electricians or Mechanics have any idea.

Cheers.

Yeah mate, figured no-one else had this problem... Its f#$&^d!!!

Just hoping that someone knew wat was going on - considering this is a Skyline website and ppl CLAIM to know wat they are talking about!!

Thanx anyway.

Your car is fu(ked,

Try gapping your plugs down, my car was stalling and switching off...perhaps it is that?

[V8skylineMAN]

sounds to me like your computer is overheating....my old c210 does that.....hot hot weather and it just shuts down

this problem was happening with my soarer, and I realised that it was my amp power wire had got melted over the back seat, and was shorting out.

I guess try to look at all obvious things - check wiring, batt terminals etc

Yeah thanks for that... Just in case i didnt know!!!

Besides the blatently obvious of it being a pain in the ass, the fact that ppl look at Skylines and it stalls just about anywhere makes it a bitch to go anywhere without having every1 laugh at ya!!! Fun and games hey??

Yeah had thought of that but when it turns off the electrics stay on so it wouldn't be a short...

Had about 1001 ideas of wat it could be but so far nothing, revs used 2 be unstable 2, changing between 300 - 2100 all the time, so i thought the turning off could have been related but found that the idle problem was just an average attempt to re-connect the RPM wire!!!

Thanks for your suggestion anyway.

Already been done, they got replaced and set! So unless the mechanic is completely incompetent it ain't gonna be that!

Cheers.

what do you mean by driving? are you torkin bout cruising, at lets say 80Km/h and the whole thing goes off? or during gear changes?. more info please

[(B1) MR_fanny]

i dont think youve clearly stated your problem for someone to actually give you some worthwile advice. yes this is a skyline forum but we cant read minds:D like the post above, does it die in the ass while ur driving, stopping at the lights on idle??

[rutelz]

Sorry guys - probably 2 vague, but was pretty sceptical from the start...

Alright this is what we're talking about:-

It has turned off while cruising or idiling - these 2 are the most common.

But it also has occasionally turned off on takeoff, or breaking hard!

The only time it NEVER turns off is when i'm really giving it to it.

It also seems to flat spot (if that's what you'd call it) i'll be driving along and it just stops responding for maybe 1 or 2 seconds, no matter how far the accelerator is down it does nothing, then it will kick back and keep going - it almost seems like it is trying to turn off... If it does this a couple of times, all i have to do is put it in Neutral while driving along and the revs drop to 0 and she turns off.

Electrics stay on though so i've ruled out a short, it also starts up straight away 2.

Another thing that it does is if I'm driving on a warmish - hot day, the flat spotting will occur and if i can manage to keep it on, the next time i go to drive it (no matter how long it is after it) it plays up, almost like its got a memory (thats where i was thinking the ECU)

It's very common during the warmer weather, almost unheard of during the colder - and its pretty much got me fu$&@d...

That's about it...

Hope this helps, if u need anymore info let me know...

Thanks all!!

Yeh no problem, sorry i could not be of more help...but im learning

[LastTemptation]

it sounds like something i read on the forum about the fuel pump earth or sumthing shorting out.. finding the earth and reconnect it in a better location.. worth a shot. also check that your spark plugs are screwd in nice and tight.. disconnect and connect your battery after you try it.. hope this helps.

I'm no expert, but have you checked for leaks along the intake system? If unmetered air is getting into the system after the AFM, then that could make it run shit. A celica I owned had a crack in the intake plumbing and the bastard would not idle, almost dying all the time and bunny-hopped on take off.

My r34 did that - was the fuel pump.

Edit: The car did it around 4-5k revs.

Yeah already had the fuel pump replaced... Still does it!

What computer are you running ? Stock ECU OR Power FC ?

[yogi000]

check for vacuum leaks?

What type of BOV?

try disconnecting various engine sensors to see if they make a difference?
