99 Honda Accord V6

[Squshiee1]

Hey guys, im looking for some help with an accord. Im hoping that some of you guys know a little somthing about newer hondas.

I have theses codes P0300 - P0306 Which says there is a misfire in one or all of the cylinders. And a pending code for P1399 which is a code for multiple misfires.

So the car runs fine but the vtec wont engage, and if i have the car at full throttle it will hold at 5000 rpms and wont shift and also losses power.

just wondering if anyone has any ideas,

I am getting ready to work through a misfire on my Tacoma, since it popped up similar codes. Apparently the code means that the cylinder didn't fire, not necesarily that the spark plug didn't fire. This can mean numerous things, but often times is a spark plug misfire, or a injector that isn't working correctly, leading to know ignition in that cylinder. Those are the 2 easiest fixes as well. Hope that helps some.

Can sensor maybe ?

The misfire and random misfire codes are because of valve adjustment. See it all the time, you will find some of the exhaust valves to tight.
