    Get the fuel filter checked for metal particles. I had the same symptoms
    when the fuel lift pump (in the tank) started to break up. It seems to be a
    common problem. Don't use it more than you have to because it will only
    get worse.

    I hope my suggestion is wrong because it can work out expensive. The
    Peugeot recommended method is to replace everything from (and including) the
    tank to the injectors and I was quoted £3,500. Fortunately a relative who
    works on diesels did much what you suggest, i.e. replace pump, flush out to
    filter and replace filter. Even then it was over £800 as the pump alone is
    about £500, I have seen other posts where people paid around £800 as well..
    If this does prove to be your problem it depends mainly on whether the
    filter has been compromised as to how much needs to be done, certainly if it
    has reached the high pressure pump and injectors you will have a headache,
    but I definitely recommend a good local mechanic over a dealer. Like I
    said, I hope I am wrong.

    It's a similar price here, in France for such operations. I know a guy who
    had the same problem on a 307 HDi (he complained about a lack of
    performance, and they found metal bits into fuel filter housing), replaced
    all the circuit two or three months ago, and although car was far out of
    warranty (yr 2001 307, 1-year warranty), the injection system swap was free,
    Peugeot paid for it all.
