Did you ever figure out what was wrong becasue my subaru is doing the same thing

ok i just drive my legacy to work and home everyday and it hasnt given me any problems until the past few days. i bought it used about 3 months ago. the guy told me that the old owner had sold it because it had jumped time. the dealer fixed the problem and it runs like new ( and it has ). now when you step on the gas just a little for like 6 seconds all of a sudden the rpm decreases and it sounds rough and the egaust is louder. the check engine light turns on when this happens. after a while of doing this the engine stops missing the cyclender and it runs perfect again and the check light turns off. i have replaced the spark plugs and gaped them right and i have replaced the spark plug wires. problem is still there what do i do???????? i need help NEW POST!!!!!!- i have found out that my underdrive pully is bent and is moving all around and i need to get a new one. but people tell me that if it still moves around after i replace it then my crankshaft is bent, but i dont think that the crank could be bent, if it was wouldnt it be leaking out of the main seals???
