hey, i was just moving my car out of the garage just now, and i noticed somthign a little worrying. I was stationary and idling for a while, with the clutch disengaged, and the engine started dropping in revs to like 200rpm then shooting back up to about 400. it did this for a while, i put it in neutral and brought the clutch back out and it sort of stopped. Nothign like this has ever happened before, it still idles smoothly and it only has 140,000km's on the clock.
What do you think? dirty injectors or something? i've noticed very tiny, tiny flatspots in the 1000-2000rpm range..the ones that last for half a second or less..
time for a service, or something more drastic?
