97 CRV, Check engine light is on steady at idle, but blinks at road speed. Shows only a random misfire code,(ONE CODE ONLY) but misfire goes away at 1200 to 1400 rpm. Have replaced plugs,wires,cap,rotor botton. All other inducations suggest ignition coil? Any suggestions or comments?

There is a relay mounted way up under the dash on the driver side. It is about 1"x1"x2" and it says Mitsuba on it. This is the PGMFI relay, sometimes called the main relay or fuel injection relay. It is very likely the problem. You can buy another one, or there was a bulletin on how to repair it. You need to take it out, pop the cover off, and resolder the cracked solder joints on the pc board that the relays are mounted on. Really not that hard if you have a little soldering experience. If not, just buy another one, about 50 bucks.
