2000 Honda CR-V Question: Misfire codes and rough idling at stops

 

Question

I have a 2000 Honda Crv with about 201000 miles on it. Runs great at higher speeds, at low speeds in town and at stops runs rough and shakes. Codes on scanner are the P1399 and the engine 1 misfire codes. We have tried the tune up items such as plugs, wires, distributor cap, air filter, fuel injector cleaner. Runs a little better but still the rough idle. Not sure what to do next. We did not use the NGK plugs because I wasn't aware that I was supposed to buy those, would that make a difference or should I go straight to having a valve adjustment done. Running out of ideas and would like to not spend everything I have on repairs. Check engine light stays on while driving at high speeds and now flashes at low speeds and while stopped.

    The 1399 code is a problem with the exhaust valve seats slipping and then causing a misfire, because the exhaust valve will not seat properly.

    This is a common issue with CRV, but with 200k, you most likely will not get much help from Honda. You will need engine repair to fix this.

    I was hoping that wasn't what it is. I guess we will adjust the valves and see how much further it will go. Not worth putting a whole new engine in. Thank you

    Try cleaning out the idle air control valve and also the throttle body thoroughly with carb cleaner, it might help, but misfire sounds like something more than carbon build up.

    I have 2000 CRV with 262,000+ miles. As my car hit 200,000 miles I had the same problem. All I do is press the button that turns off the overdrive(OD) and it no longer putters at lower speeds and idle. Hope this helps.
