Stalling..

[Damo Monster]

Hi there..

Hey my R32 GTS-t has started trying to stall when cruising at about 100ks.. It hasnt done it a lot, but it gives ya a bit of a fright when your car tries to die as your driving it on the highway lol.. anyway, it seems to try and die when its cruising, not under any great load or anything.. the cars an auto, so no change in bov.. thinking it could be a fuel filter cause im not sure when it was last done, esp because of the way it drops power very fast for about 2 seconds and then comes right.. the thing im wondering here is most fuel filters ive seen are made of like a clear semi transperant plastic.. but the on in this car is quite an old looking silver tin one.. is there any chance it could still eb the factory one or something?

cheers

it could still be the factory one, but you will find that the replacement one will look pretty much identical. it would be worth replacing either way just to rule it out. sounds a bit weird that it is only doing it at light load. could also be an AFM issue, o2 sensor, AAC valve issue.

will look at changing the fuel filter and see what happens.. the only think ive changed recently is adding a full 3" turbo back exhaust.. but that was about 2000k's ago and its only started doing it now.. is there anyway way to check the o2, afm and aac valve?

since the car was traveling at 80 -100km at the time of the drop, and so doing around 2.5 - 3k rpm, wouldnt that rule out the aac vavle? just trying to think of what might cause this so i have somehwere to start.. any input is welcome! cheers..

It won't be the AAC valve - that is only for idle control.

IT WILL NOT BE THE O2 SENSOR!!!!!!!!!!!!! A dead O2 sensor will not prevent the engine from running. It will simply cause an increase in fuel consumption (at worst).

It could be the fuel pump controller playing up. See if you can get a fuel pressure gauge set up and drive around a bit observing if fuel pressure has an effect.

The clear plastic fuel filters are for carburetted engines. They only need to withstand around 4psi pressure. All EFI engines run a metal canister fuel filter, so they can withstand the 3bar + fuel pressures.

clean your AFM, AAC valve with cabi cleaner. and try.

is your AUTOMATIC transmisson..? if so,

1 when it try to stall put it in to N

2 see how you feel. if u feel it want try to stall,

3 check your transmission fluid level.

drive or idel until engine get warm,

drive 1 2 3 and D and put in to R put in to N and leave it 1 min and check the level of the fluid. fluid level S/B in between L - H level. make sure your dipstick with no fluid bubles. if so do a transmission service.

I had the same prob with my car. hope ths will help u.
