Hi, I have a Kia Rio 2005, 55 reg (new shape) 1.4cc petrol. Every now and then the engine doesn't fire up, it cranks over fine but does not start. I have changed the spark plugs but fault still occurs every now and then. Ok for a few days then it doesn't fire up, after a few turns of the key it starts, then back to being ok for a few days again. I have also swopped key for spare, same fault. Please help??????<BR itxt="1">
