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.

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

Guys,

Thanks all ur replyes. i have sort the problum. it was my automatic transmission transmission. i was run the car with very LOW FLUID LEVEL. that was the prob. if u got a same prob with auto car. check the trans fluid. and the same time u can see the engine light is on ur dash that is ur TCC - [Touque Convert Cluth] solonoide. no doubt

thanks again

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

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.

    • The values for HID colour are also defined ~ see https://www.legislation.gov.au/F2006L02732/latest/text  ~ goto section 3.9 onwards ....
    • So, if the headlights' cutoff behaviour (angles, heights, etc) are not as per 6.2.6.1.1 without automatic levelling, then you have to have to have automatic** levelling. Also, if the headlight does not have the required markings, then neither automatic nor manual adjusters are going to be acceptable. That's because the base headlight itself does not meet the minimum requirement (which is the marking). ** with the option of manual levelling, if the headlight otherwise meets the same requirements as for the automatic case AND can be set to the "base" alignment at the headlight itself. So that's an additional requirement for the manual case. So, provided that the marking is on the headlight and there is a local manual adjustment back to "base" on the headlight, then yes, you could argue that they are code compliant. But if you are missing any single one of these things, then they are not. And unlike certain other standards that I work with, there does not seem to be scope to prepare a "fitness for purpose" report. Well, I guess there actually is. You might engage an automotive engineer to write a report stating that the lights meet the performance requirements of the standard even if they are missing, for example, the markings.  
    • Vertical orientation   6.2.6.1.1. The initial downward inclination of the cut off of the dipped-beam to be set in the unladen vehicle state with one person in the driver's seat shall be specified within an accuracy of 0.1 per cent by the manufacturer and indicated in a clearly legible and indelible manner on each vehicle close to either headlamp or the manufacturer's plate by the symbol shown in Annex 7.   The value of this indicated downward inclination shall be defined in accordance with paragraph 6.2.6.1.2.   6.2.6.1.2. Depending on the mounting height in metres (h) of the lower edge of the apparent surface in the direction of the reference axis of the dipped beam headlamp, measured on the unladen vehicles, the vertical inclination of the cut off of the dipped- beam shall, under all the static conditions of Annex 5, remain between the following limits and the initial aiming shall have the following values:   h < 0.8   Limits: between 0.5 per cent and 2.5 per cent   Initial aiming: between 1.0 per cent and 1.5 per cent   0.8 < h < 1.0   Limits: between 0.5 per cent and 2.5 per cent   Initial aiming: between 1.0 per cent and 1.5 per cent   Or, at the discretion of the manufacturer,   Limits: between 1.0 per cent and 3.0 per cent   Initial aiming: between 1.5 per cent and 2.0 per cent   The application for the vehicle type approval shall, in this case, contain information as to which of the two alternatives is to be used.   h > 1.0   Limits: between 1.0 per cent and 3.0 per cent   Initial aiming: between 1.5 per cent and 2.0 per cent   The above limits and the initial aiming values are summarized in the diagram below.   For category N3G (off-road) vehicles where the headlamps exceed a height of 1,200 mm, the limits for the vertical inclination of the cut-off shall be between: -1.5 per cent and -3.5 per cent.   The initial aim shall be set between: -2 per cent and -2.5 per cent.
