Hey hopefully someone can shed some light on this, my partner has an 02 plate focus 1.6 auto that keeps stalling, it doesnt happen all the time, more so in wet weather though. Its usually when slowing down thn accelerating off at junction etc the battery light will come on then split second later car will chug lose power and stall. I have recently changed timing and aux belt, fuel and oil filters spark plugs, exhaust and lambda sensor, also when driving in bad wet weather the engine light will come on with something o2 sensor related but clears when wipe code!!
