Valve adjustments?

Valve adjustments?
I've been dealing with the irritating misfire code (1399) for all cylinders off and on for about 2 years now. Last year I had the valves adjusted, the computer reset and all was good. The CEL has recently appeared again (same code). I replaced the coil packs but the problem persists...
I did a track day about two months ago so I guess my question is; can sustained hard (track) driving accelerate the need for a valve adjustment? My next plan of action is to replace the fuel injectors to see if that helps, but if a valve adjustment is all that is required after each track day or two, I'm ok with that.
BTW the car runs fine with no obvious symptoms.
Thanks!

Have you done a compression test?
I had that same CEL code, plus 1301, 1302, 1303, 1304...and I had a few burnt valves...

Yeah if you did one last year it doesnt need it done again for a while, even if you track it. I agree with FearlessFife, have you done a compression test yet? If something comes up weird in that, just get a leak down test done and you can find where the problem is.

Thanks guys.
Yeah, Honda has done a compression test each time the code has come up and it has always been fine. I guess I'll try the injectors and see what comes up. I guess the upside is I now have a spare set of coils...
Will keep you posted.

have you ever had an over-rev ?. Common sources of misfire cel's are spark plugs, coils, injectors, MAP sensor, bent valves.

Never had an over-rev and I had a leak down and compression test done the last time the code came up. I had the valves adjusted and it went away for a few months. Now it's back...
