Hi I've been gettin a problem where if I accelerate hard the car will stutter and misfire usually around 4000rpm where if I accelerate gradually it's ok also it can idle a bit rough too, I've changed most things including fuel pump (as this packed in anyway), coil pack,plugs etc to no avail. Dont know if it could be related but I noticed the other week the loom that clips onto the fuel Pressure centre 2 of the three wires had fraid and could of been touching, once I'd taped up it ran a bit better but still not right, a friend who's a sparky as now sorted these out properly but suggested my problem might lie in the fuel pressure sensor as these wires might of shorted it. The car runs exactly the same with the clip unplugged which makes me think it could be this. If anyone has any suggestions I would be grateful cheers
