Hi, I've started noticing a loping feeling while idling in my '05 325Ci. Can't really hear anything, but the car feels like it's shaking. And the shakes usually happen one at a time, in a random pattern. I can see minor fluctuations of the tach when its happening, maybe 100-200 rpm.
I have an E46 sedan but i don't use so much my car,
annually i drive arround 5-7k kms.
Although i change my engine oil x2 per year every 6 months or so,
i haven't changed my sparkplugs for 2 years now,
and with them,
i had driven the car for arround 12k kms.
Should i change them ?
