Hi Guys. Have recently noticed this in my ride during idling. Engine would hum smoothly, but every 1-2 minutes, can feel a skip/hiccup in the rythm. There's no lound or audible noise, but can feel the skip through the vibration of the car (hand of steering wheel). It goes something like this: "brrrm, brrrm, brrm, brrrm, brrrm, .. .. brrrm, brrrm, brrm, brrrm" - There's no stalling. Engine contiues humming without dying - Engine idle rpm is constant (must check again to be sure) - Using RON 95 I'm worried that this could be the beginning of something and hope to address it before it becomes a problem. Based on my layman's guesses, could be the following ??? - Fuel need to be higher octane. (I'm using 95 as recommended) - Need to service and replace engine oil. - Fuel Filter clogged. - Engine needs tuning. My ride is due for servicing in another 500km. So thinking of getting this looked into at the same time. But must know what to tell them to avoid being "smoked" and getting a big fat bill for unnecessary part changes.... Any experts please feel free to offer advise. Thanks In Advance
