have any of ya deal with the issue on the v6 misfire cylinder #3. And after doing the update and replacing the plug. In the past three months i have done about three accords and one oddesey tech line recommends to replaced the valve seals and inspected the top of the piston on cylinder #3. i have to replaced the seals and replaced the piston rings on the same cylinder. So my question to ya is if ya have deal with the same issue and do ya think that would finally fix the problem one's and for all.

I would do a compression check first. This will give you an idea as to if the valve seals or pistion rings are worn or not. Thats just my 2cents.

I would have to agree. If compression is good that would mean no reason to rering a motor. have you done a valve adjust? if they are to tight on that cylinder would throw off map sensor readings.

I haven't yet. Replacing plugs and update fixed so far.
