so here's the deal. i own a car. the car was running mint until about a month ago. now after about 10 mins of driving the revs drop and i can't even let itidle (at lights etc) without it dying on me. i have to restart it each time with my key. drives fine when it's actually in motion but soon as i have to stop it cuts out! when it does this i can't turn the steering wheel either, so yeah, it's kinda dangerous.the weird thing is that it runs fine and idles fine and doesn't die on me for the first ten minutes. on my way to work every day in pretty much the same spot it starts playing up.any one have any ideas!

An air leak between the air flow meter and the manifold or dodgy throtle position switch.!

ok so the one other person i've asked about this mentioned air flow meter as well. i'm guessing this might be where the prob is. i know nothing about cars at all, but if two random ppl mention the same thing then it sounds like it might be the prob. thanks andrewph, will look into this

could be water in the fuel, if so pour some meths into the tank and see if it gets better

It may not be the air flow meter itself but the rubber pipework that goes between the meter and the engine on many '90's Mazdas was shocking for going hard and splitting open over time, made worse by it being stretched and bent when checking or changing the air filter.The other possiblility is that the throttle body needs cleaning out and perhaps the base idle speed reset as needed, again this is common on injected Mazda engines of the era when they get up in the kms, they don't pass enough air through the throttle when warmed up and thus you get stalling.

Appreciate your advice, cheers.

+1 I agree on the rubber pipework. I have found more problems caused by vacuum leaks like that with perished rubber hoses than ones actually caused by air flow meters. Not saying its not the airflow meter or something else, just check the inexpensive and most likely option first.

My B6 twin cam is doing this too, I havnt sorted it out yet, I have made a temp fix by adjusting the throttle butterfly screw but it makes it rather difficult to start.
My symptoms are exactly the same, once warm it wont idle. I will be checking for vacuum leaks too
