ok, so i was going home coming from silver spring, md. the car was fine when i left from md, however when i got home, i noticed that when the engine had reached around 2700rpm, a tapping sound was apparent. i had also noticed that approx. 30-40% of power was basically gone. So i reach home, turn off the car, waited a few minutes, then turned it on again, and right when the engine turned, the nocking sound was load & intermittent for about 6 secongs, then it got quiet. So i gave a little gas, and agian after 2700rpm, the sound waws apperant. So i check my oil, it was low, put 2 quarts in, & it was still there. when i started it up agian, the maintence light was blinking 10 times before it turned off, ususally it would never blink like it did today. SO i was wonderin if anybody could help me out diagnoise this problem and was wondern how much it would cost. THanks
