engine running rough

  1. #1
    ive got a Peugeot 106 XSi with a 1.6 VTr silvertop and Pug Rallye inlet manifold and ECU .

    The engine conversion was done by the previous owner and the wiring is abit shabby. The other day she started running really rough, as if it was only running on 3 cylinders and little power.

    Does anyone know what could be making this happen?

    I was suppost to be having a mechanic come and re-wire the engine loom but that hasnt happened yet, so i havnt looked at anything myself.

    Could it be: Injectors, Spark plugs, Dirt in Air intakes, AIC, lack of vacuum or maybe even the HT leads, or just down to the poor wiring?

    In a word Yes.

    You'll need to narrow the problem to one of these areas:

    1) fuel/air mixture
    2) electrical
    3) compression
