Common VFR 2002+ problems:
*thermostats are notorious for sticking, I replaced mine, it was stuck slightly open.
*Fuel injection system has a few lean spots, not terrible though.
*Speedo is 10% off, even on the newer ones. It is +10% off.
*VTEC power surge @7000 RPM takes a little getting used to, again not a big deal.
*You have to wait for motor warm-up before you get engine full power. Coolant temp needs to be at 150* F. Doesn't take very long. Essentially the VTEC doesn't engage until 150*F.
