Hi everyone hope someone can help me with my car problem ???
I was driving today for about 10 miles average speed lol and the car started to missfire and lose power then a rumble started from the engine and it felt as though the car would stall, ive had the cambelt checked and its not loose the oil is not frothy or creamy i have had antifreeze over the cold period. the knocking is not continuous and seems to idle ok for a while then suddenly a knocking from the engine and a missfire starts.....any ideas?

the coilpack could be causing the misfire,you really need to get a diagnostic done to find any faults,is knocking noise coming from top or bottom end
