Default Rough Idle

My 2000 CRV has 59k and has started to run rough at idle, then the check engine light came on. I went to Autozone and used their equipment to see what is causing the light to come on. It said I had 6 error codes. 4 of them were PO301-304 (individual cylinders misfiring) then there was code PO300 (random cylinder misfiring) and the last code was P1399 It said to see manufacturer specific DTC. The Autozone people could not tell me what this meant. My mechanic said it sound like a cap & rotor problem, and he also reccommended replacing the PCV, fuel filter and a valve adjustment. He was not sure....I ended up at the dealer, the advisor scheduled me for a valve adjustment (Its been 30K). Any suggestions????

Your issue sounds like mine which I just posted a couple of hours ago (It just went haywire). Do you happen to have a really strong sulfur smell? I am betting it is due to a portion of the computerized electronics - not a valve adjustment. Mine came on suddenly. I am due at the dealership tomorrow am. We will see...

I had similar issues like yours, Everything your mechanic mentioned I did myself (except the Valve Adjustment). I also changed the plugs and wires and because I use a K&N filter, I cleaned the throttle body with the Honda spray cleaner. No more Rough Idle and the car runs as good as new.
I also changed the rear diff fluid and flushed the tranny since I was on a roll.
My CEL ended up being a worn out gas cap seal. I went ahead and bought one from PepBoys.

Let us know what you end up doing to your V.

yea cleaning your throttle body makes a world of a difference. Also maybe replace your spark plugs and look for warning signs on them. But ONLY use NGK plugs and i mean ONLY. Any other plug will not run right no matter how "high performance" it is. My friend who owns a performance shop had a LS/VTEC go back cuz he was using Bosch Platinum 4 plugs, it warped the head it self. NGK plugs are even shown to give you more power than those Iridium plugs and are only like 2 bucks a plug.

Please clarify ... I think NGK offers iridium plugs now. Do you mean to use the same NGK plugs that came frequently stock with the engine? Would you stay away from Denso? (My car came delivered with Denso plugs when new.)

Well prior to my appointment, I bought a can of throttle body cleaner. Cleaned it a few times, cleared the 6 codes and went to the dealer. One mile down the road the check engine light came back on! I went to the dealer, I had shut the engine off and restarted it for the service tech. Guess what...NO LIGHT! Honda did the valve adjustment and afterwards the light came back on, The mechanic said it was running fine.but they wanted $$$$ to clear it (all it was was a misfire on #1, The valve adjustment took care of it.) I cleared the code myself and It runs great.
Also... I changed out the rear diff fluid and NO MORE NOISE !!!!

Thank you everyone for your help!!!!!
