Misfire Problems
Hello everyone. just have a quick question regarding the codes that i pulled from my honda. these are the codes:
p0300(multi misfire) thru p0306(misfires) & p1399(control ignition system OR misfire)
now i know that these are all misfire codes but what is awkward is the vehicle doesn't seem to run rough at all. The vehicle is my wife's 1999 Honda odessey.
can anyone help me or has anyone gone thru this and have any helpful advice? Thanks everyone.

Re: Misfire Problems
um yeah you are way out of where you should have posted this but ill play along.
p1399 is more than likely causing the p0300 and p0306.
this is where i say you need a service manual to look at the trouble tree.

Re: Misfire Problems
It could have misfired at one time causing the code to be stored, even though the engine currently runs fine.
I'd do a tune up and use a scan tool to clear the codes

Re: Misfire Problems
the problem isn't a need for a tune up, you need to have your Honda dealer plug in and record your freeze data. specifically your EGR lift value and throttle position sensor value. there could just be a problem with the egr valve. basically what we do is compare the freeze data to what the vehicle is actually doing. I have seen where the freeze data tells me the egr lift value was at 40-50% when the vehicle was sitting still. if I were you then just bite the bullet and go to your dealer. you could end up spending money you don't need to spend and still never fix the problem.
