Engine and RPM problems - 2002 Subaru Impreza 2.5 TS

[djp]

Has anyone experienced any of the following problems with their Subarus?
They happen to me sporadically (sometimes more than 2 months will go by
before I see them again).

- When idle, engine RPMs go from 500 to 1500 and back again. This repeats
2-3 times and then the car goes back to normal.

- Car just doesn't want to start. I have to try 2-3 times.

Thanks

Start by cleaning the throttle body. Assuming you've had a tune-up in the
last 25,000 miles or so.
