I've got a 2002 Subaru Outback with what can best be described as a "galloping idle". The car runs fine (except for an occasional hesitation at acceleration), but when the car is idling, I can feel like the engine is revving up and down. When it starts, it's quite regular. Sometimes it's subtle, sometimes it quite pronounced. Sometimes, it doesn't do it at all. Naturally, that's usually the case when my mechanic is driving it.
I've had it in the shop twice and both times the mechanic has found nothing. I've replaced the fuel filter, the spark plugs, checked the air filter and flow, changed brands of gas, switched to higher octane levels and added fuel system cleaners. None of which have helped.
Has anyone encountered something similar to this? Have you figured out what may cause it?
