Engine Cuts Out After Boost

[gach2]

My r33 last night started to play up just after hitting boost

id rev it up to around 4500 and change gear

and upon this the engine would would cut off, power steering turns off

and 4 dash lights come on

it kept doing this whenever i hit boost

if i didnt hit boost and shift before it did, the car drove fine

tried again this morning and the boost came on fine (bit off a boost leak but fine)

took it to my mechanic and it was how i drove it this morning

he had a quick look over and found the afm lookd dodgy (been resealed with silicon, the pcv valve that attaches to rocker cover had its grommet broken

and also the bov it stock but has been blocked off)

as i have a spare afm and rest arent big repairs ill get this soon

but if anyone has ideas to whats happening above (with the engine cutting off when hitting boost)

let me know

thanks

Is it a standard ECU? and how much boost were you running? might be R&R mode.

[gach2]

sorry as above i know i have included as much info as i should

whatever you want to know

let me know

ok standard ecu, 7 psi

after searching the forum thats my first though although was told that r&r wouldnt really cut out the engine (like it would still come back)

also most of examples of people with this forum wasnt on 7 psi

as for mods to vehicle

just exhaust, cai and pod filter and fmic

just changed the afm

havnt yet tested the car

but found the following differences on idle

before when i moved the afm and piping the car changed its tone or idle, now it stays the same

also before when i unpluged the afm the car took a few seconds to die

now it dies straight away (which im told is normal)

on another note

proabably wrong place to ask but wheres the best place to buy the piping for the bov - and the grommet for the pvc valve

Im getting a feeling your fuel pump might be on its way out? Im guessing its a stock pump? May not be delivering the fuel fast enough, then when changing gears there is no fuel in the line? Just a stab in the dark.

think it was the afm

as no this problem dosn seem to be there anymore
