Does Any one Here have an idea what to do when cleaning the egr valve and passages? Is there thread that can help me do this i know where it all is and stuff i just need some guidance................thanks guys!
Have you investigated the one-time emissions repair by Acura? Not sure if it's applicable to 96, but worth a check.
If you know where EGR and EGR manifold is located, it's a simple matter to remove, clean passages w/ throttle body cleaner and mechanical tools (stuff is pretty hard), and reassemble. I haven't done a 3.2TL, but have done a couple of 4-cyl Accords. The outlet holes into the intake manifold passages may be completely blocked and require cleaning w/a drill bit. The hole size may vary from hole to hole (balanced EGR flow sizing). You likely will need a new EGR and EGR manifold gasket. Best to get before you start. Presumably you have an "insufficient EGR flow" code?
good luck
