R32 GTR Stalling/Cutting out..help

[lang]

hey,

When driving my R32 GTR it keeps cutting out (similar feeling to running out of fuel) and when it does this it wont idle it just stalls, then ill start it again and it will idle ok and drive normally for a bit (seconds to a minute or so), then start cutting out again

the feeling when it cuts out at say 2500rpm is very similar to running out of fuel in your tank but a tiny bit different, runs really rough like its dropped half the cylinders and looses all the power completley. its not persistent tho and when it comes good it runs perfectley for a little while (enough to limp home on).

my guess is its a fueling issue of some sort, has anyone come across this problem before?

Cut out at 2500 rpm says Air Flow Meter(s) stuffed.

Another possibility is a dying ignitor module (they become susceptible to heat, and stop working until they cool down a bit).

the ignitor module does look a little corroded on the outside, ill take a better look at it

Hey i got the same problem with my 33, but my one is from 3000 rpm travelling at an average st speed, pop it to neutral then the idle jst drops down as if its gonna stall then at one - three times it did stall, but wen i put it back to gear it started running again =S

check your cooler hoses. thats the first thing i would (and have) assumed.

i have an r32 89 rb20, and yes it is an auto. It had sort of the same prob. kept stalling on me, it still does. but yeah cruisin down the highway it would just cut out...and the kick back in and be fine. The other day it just kept stalling and when it would idle i would try and rev it, when it got to 2500 it would hit like a rev limiter and just back off..and then it would stall. So i would let it sit and it would be fine. But does that explain why it wouldnt do it all the time, and would it be why it does it when i am going down the highway??

EDIT: Someone suggested it could be the crank angle sensor....but the air flow meter sounds interesting....i reset my ecu and it was good for the rest of my trip, so that might be a temporary solution.

Hey i had that before, but i fixed it now, its really quite simple if you dnt know where to start. Firstly do you have an aftermarket BOV? Rev it to 4-5000 rpm then check if the engine is about to die, do it for a cpl of times. If this is the problem then jst swap ur stock bov then try it again if it doesnt fail its definitely your BOV.

It could be alot of things but i know the GTR's have a limp mode built in to the ecu programming. That will limit the revs to 2500 if sumthing is wrong...

turned out to be some dodgy wiring in the loom

Yeah man thats what my importer said. Yeah but sometimes it does not just limit the revs but like cuts out at the 2500. and sometimes it will limit it. I wiped my ecu and it still does it though. So has annoyone got any other ideas.

Lang: In simple mans terms, the loose wiring in the loom...where do i find the loom? :S

[lang]

the loom is the wiring loom which afaik just means all the wires that go from the ecu to various parts of the engine bay, allthough i think in my case (a freind fixed it) it was to do with the wiring from the airflow meters to the ecu.

ok thanks you

I have a very similar problem

the car stalls "randomly", especially after I hit bumps.

monday, I went slowly into gravel, turned the car off, started it, and went about. 15 secs after.. engine died and didn't start again after 5 tries, Fuel pump was priming so that wasn't the prob. I have a recirculation BOV so if it leaks, it goes in behind Z32 MAF. I tried following the wire loom from the connector and it passes right under the A/C oil canister... and the loom was somewhat filled with old oil.

I will for sure to to follow that cable tonight and make sure everything is secure and undamaged.

My car is not in limp mode, I can go to redline with no trouble and with quite a bit of power.. if it's not acting up hehe

I do hear misses at any rpm range... like Highway... at 3000 it will do it but for like 1/2 sec and the engine "starts" back. I will also clean the MAF tonight with electircal contact cleaner

and verify every air path
