Hi brnnsoul,

P1399 is a temporary code for misfiring.

Did you check the spark plugs and wires? Could be a failing ignition coil.

Was any other codes retrieved?

Another item to check would be a lazy O2 sensor. Get the freeze data if possible.

Thanks again. No that has not been checked. I will have it checked monday. I did not look at the machine that retrieves the code, but was told that was the only code that came up. This only happens once and a while. The time it threw the code, I was stepping on the gas rather hard. It just wouldn't go, so I stepped harder and of course the check engine came on, I took straight to the mechanic. That is when we got the code. I hope I am not confusing you. It only threw a code one time. But the problems is intermittent.

Will also have the 02 sensor checked

Again, thank you for your time!

You are welcomed.

Temporary means it is not a confirmed. It takes a two trip fault, ie the fault must occur 2 times before the the actual misfiring code would be detected.

I have encountered a few cases of the symptoms decribed which were caused by a lazy ( faulty ) O2 sensor. Some scanners were not able to detect the problem so you might need to use a different scanner to see if it shows anything.

P1399 on a 99' CRV? The B20 engines in the 1997-2001 CR-Vs are known to have problems with valves tightening and then 'burning'

The Cam profiles don't let the exhaust valves enough time to cool. So it leads to them cooking.

Have valves adjusted LOOSE and inspect for damage.

AND THANKS HONDA

To be able to save me a little money my mechanic would like to know if you have an idea of which 02 sensor to replace, or just go for both.

So hard when there are so many things it COULD be. No matter how hard I tried, I could not get the stupid thing to throw a code again!

Thank you for all your time and patience.

If it is an O2 sensor problem, it usually is a fault with the primary HO2S, the one located before the catalytic converter.

Is the engine idling smoothly? If not, then as ej00807 mentioned, get the valve clearances adjusted.

Hi afrodevil666,

P1399 = Random Misfire. This is usually associated with other misfire codes such as P0300, P0301, P0302, P0303 etc.

Correct the P1399 is just stating that there are misfires on various cylinders. We need to diagnose the other misfires and this will just go away.

If you have a misfire on cylinder 2 then just address that and this other will go away.

Here is a guide that will help with this.

Just make sure you check compression as well as this can cause misfires and most overlook this.

Let us know if you have questions. Thanks
