I have been experiencing a few probs with my Stilo 150, it only happens when the engine is getting warm, it starts fine and runs fine when hot. But between 2-4 mins after start up, I can put the accelerator to the floor and it will not rev at all, just stays at tick over. This is very embarrassing at junctions, and the only way to get it going properly is to turn the engine off and re start, maybe that will work 1st time, maybe not. Fuel is fine, new filter and has Millers it in. Any pointers to save the reputation of me Stilo would be welcome.
