have your codes cleared and as soon as your light comes back on get it checked right then. usually the first code that pops up is your problem,. and can cause faulse codes to follow. check your mass air flow sensor,. make sure the breather tube is on good and no cracks or tears in it. check fuel filter also hope this helps you in the right direction

I had the same issue and the same code along with the misfire codes too. I replaced the spark plugs and I have had great success. Change the plugs, wires, and maybe the distributor cap :)

The P1399 random misfire along with one or more of these codes: P0301, P0302, P0303, P0304 -- indicates a problem with the valves. The B20 engines in the 1997-2001 CR-Vs are known to have problems with valves tightening and then 'burning'.
So the first question is when was the last time you adjusted the valves? If you don't know or never have, then have them adjusted. Soon...
