Let me tell you something, mechanics are pricks........even if your valves are not damaged, he wil say they are just so he can get more money...My advice, have someone check this out that you know will not gyp you ( a friend, etc. that knows about acura). One more piece of advice....I had the same thing happen that you did, but it ended up being that I needed a new distributor, cap, coil and rotor. Make sure you check this out before you go and do anything drastic.
