clio 04
So I was fitting my sub and amp wen a wire sparked, causing a fuse to blow in the fuse box. I found it sAnd replaced. But ever since, when I'm stopping at some lights or a roundabout with foot on clutch its reving at 20 on the rev counter, then I try to pull away and it dies. Won't start for a wile but then drive fine. I can tell wen it guna happen as the gear stick feels different ie I can feel the engine in it. I have 04 plate
