Hi Sometimes when the engine is under load there is a strange missfire. The engine noise goes up for a second like revving, but it feels like the engine is braking? It just happens for a split second every 5 seconds or so. If I turn the ignition off and on again it usually sorts it. Any ideas? Thanks in advance. Jamie
I had this on mine, it was the main pump cutting out due to fusebox damage. worth a look anyway. the relay socket had corrosion and the fuse socket had melted!
