my 2000 accord just all of a sudden got gutless i mean geo's pass me on the freeway, anyway i had a cel reading for the cat, had it checked and was told it was not bad, changed both O2 sensors, front and rear, light went off, still gutless, did a tune up, checked mileage at 107,000 and got timing belt, balancer, water pump and gen belts all replaced and its still runs like a moterhome with a 4 banger, no codes , what should i try next i am at a loss????
