I have a 2002 VTEC motor and whenever the engine hits 1600rpm, it starts to miss a little, The motor is fine otherwise throughout the entire power range. I did the obvious and replaced the plugs with BOSCH +4's and since there is no distributor, wires, or coil, you can't really do much tune up wise can you? All my other Hondas were not VTEC's and I never did more than plugs and ran the cars up to 180K and beyond. Any ideas would be great.
