Every time i start my 1.7 diesel corsa b, it is really lumpy. It also has a random misfire, especailly at around 1200 rpm. this gets better as the engine heats up, but never goes away completely. Its also been using noticably more fuel, and smoking slightly at higher rpm. also feels less powerful especially when cold
just had new glow plugs, oil, transmission fluid, and battery.
when i changed the glow plugs i noticed that two of them had some stange deposit on the end, and one had a little tiny bit of melted metal on it.
a mate said it could be a melted piston ring? i dont know but i NEED this sorted
