I’ve never heard that. heres a link thats close to what you got. It should be removable with taking the head off.C8-)
Hey bud. Here’s Eric’s vid on a 4 cylinder Accord EGR passage cleaning:

And another on a V6, which I know doesn’t apply:

Hopefully these point you in the right direction, and notice there is no pulling of the heads. Good luck bro.
Thanks for the response guys. This engine isnt the same as the old ones. I miss understood what I was reading, the head doesnt have to come off to clean the EGR passages. I would have to take off the intake though. Seems the EGR passages on these engines are on a “spacer” between the intake manifold and the head. So has anyone used the SeaFoam in a vacuum line?
+1 on not having to remove the head to clean those. Just curious do you have a code for insufficient flow?
Nah, just being pro active. But I dont want to take the intake off so…. Really just need to clean the IAC valve and the thottle body. Keep getting random missfires.
Heres a video to help narrow down the random misfires

I agree. Are you getting a CEL? Taking the intake mani off isn’t a horrible job, you just have to be careful. Why do you think you are having misfire issues?
Don’t fix what ain’t broke, words to live by if you asked me. As for the misfires start with the ignition system, it’s very important to use OE parts on Honda ignition systems so be sure to use NGK or Nippon Denso spark plugs and nothing else. If you don’t find any issues there you might check for vacuum leaks.
http://www.youtube.com/watch?v=9CPqbaSgcok+Believe my ignition system is fine. I will have misfires on cold start up here and there on all 4 cylinders. Idles a little rough sometimes. Runs great the rest of the time. I did get a code for the EVAP system yesterday. Could the EVAP system cause problems like this? The first thing I am going to do is clean out the IAC valve. The car has 260k on it so it wont hurt.
Evap code shouldn’t cause idle issues. Intake leaks, poor spark, air in the cooling system etc could though. I’ve heard (read) Eric say repeatedly that he’s never had much luck cleaning IACV’s though. Just a heads up.
