Car Stall When Braking

[koduRB25det]

i got a r33 gtst [rb 25det]. i bought this couple of months a go. since that day, i install a aftermarket intercooler and change the timing belt as wel as spark plugs gap to 0.8 mm . from last 2 week when i brake the car suddenly [coluor lights etc] car revs down 0 and go up 8000-1000 [cant explain exacly...] and car stall. i can feel some thing cuts off. when i start again it will starts no probms.

i allready cleand the AAC valve, AFM as well.

somebody can help me to sort this out is highly appreciate.

My car is doing the same thing, since I cleaned my afm and replaced the intake pipe. Its definitely running lean off throttle causing the occasional stall.

Have you tried resetting the ecu? Make sure all the hoses are connected, like PCV as this will affect idle too.

Does the pedal sink all the way towards the firewall when it stalls, or does it stay consistant? Might be worth looking through the workshop manual, even the R32 one in the Brake diagnostic section.

Could be a brake booster vacum leak. Check it out.

try the reset iac valve procedure, it in the engine manual, my car use to do it aswell, if u try realeasing the throttle a bit softer or harder ull find thr prob goes away, u got a stock bov

if it only does it when you press the brake pedal then it is going to be in the brake booster. if it does it when you lift off and don't touch the brakes then it isn't the brake booster.

the brake booster has a vaccum line going to it to give you better braking. if the line is damaged or the diaphram in the booster is damage then when you push the brake pedal you are altering how much air the engine is getting and making it stall

hey i got the same problem... can you tell me where the transmission fluid container is located??

[mad082]

i'm not sure if they have a seperate resevior or not. generally most cars will just store all the fluid in the gearbox and you simply pull out the dipstick for the gearbox and tip it in there. it's been a while since i had to top up an auto gearbox so i'm not 100% sure on that.
