Sorry if this is vague, I don't know very much, but I'll do my best. I want to have as much information possible before taking it to a garage to do anything. I have a 2003 Peugeot 206 1.1l which has done ~27000 miles. It's running pretty well, on the whole and the exhaust has recently been replaced for the 1st time.
On the way to work today, near the start of the journey, when I stopped in a queue of traffic the engine quietly cut out with no warning or stutter. I restarted the car and it was fine for a little while (including stopping again), and then it did the same again when I stopped. This happened for around about 20 minutes, with 3/4 'stalls' out of 9/10 stops.
I had a quick look on the internet, but not knowing the first thing meant that I couldn't make an informed judgement really. This forum post, saying that it turned out to be a faulty engine control unit seemed to be the most similar to my case, although it's an older model. Another theory, based upon asking around, was air in the fuel line, which sounds like something that I might be able to fix myself if I can confirm that it is that somehow.
Does anyone know what might be wrong, or how to find out what might be wrong, before taking it to a garage?
