Intermittent Engine Problem

[R32GTS-t RB25DET]

hey, i was playin with my R32 GTS-4 the other day, and i noticed it kept turning off by itself.... it didnt seem to idle unevenly... just turned off as though id turned off the key???..

this isnt a constant problem, sometimes i start it and it'll run beautifully, then other times... turns itself off and wonnt rev over 2500.

car specs are:

RB25DET from a R33

turbosmart e-street 40 boost controller

aftermarket front mount 'cooler

absolutely any help would be fantastic as i have no idea why this is happening.

thanks

have you done anything to the car recently?, btw welcome to the forums, is it a 2 dr or 4 dr btw?

Try AFM, usually cars don't wanna rev if AFM is faulty. Probably stalled the engine from the inability to read air flow or something.

well, i crashed it 5 months ago, and only just finished fixing it 2 weeks ago, and this problem arose... im guessing it has something to do with the var sitting around for 5 months doing nothing?

btw its a 2 door

hmm, but it doesnt idle rough, and will happily sit there idling until it has a PMS fit and turns itself off.... is that normal?

thnx

- edit -

today it started stalling and stuff, but would still rev over 2500.... it'd redline actually... im thinking maybe a fuel pump? cos immediately after stalling... unless u let all the buzzing get over and done with (a pump of some sort... fuel i guess....) it will just stall straight away...

also the exhaust/cat light comes on in the dash... but the car stalls after a minute or so..... ????????

WTF???

ok i think i found the problem.... a 1/2 unsealed intercooler pipe... fixed that and all seems good...
