Question about 1997 Subaru Legacy
When cruising at 100klms and increasing speed without changing gears the engine will cut out at 3.5 revs and the engine light will come on. after this the engine wont rev any higher if you increase acceleration to heavy. if you just increase the acceleration ever so slightly it will increase revs. When you turn engine off and back on it will remedy the problem.
Check Fuel pressure regulator by disconnecting the vacuum hose. Didn't say what year you have, yet the timing belt can also cause this as I had similar problems on an 87 and the belts were loose and floppy causing erratic firing/idling. A little easy trick to check timing belts without taking any parts off to get at timing belts, is (and no one knows about this one, hee) with a timing light!

Give it a transmission tune-up, Dexron III oil, Lucas for transmission and transmission filter. Check the fluid level, restart the computer go for a ride. Check the fluid level again and continue to drive, it'll get better when the computer sets. I suggest you change the air filter, engine oil and filter, fuel filter etc. Just give it a tune-up!
