Default How to clean EGR ports for a 94 accord EX VTEC

I've been meaning to clean the EGR ports for the longest time now. But looking at the fuel relay and all the things I would have to remove, I dont think I can comfortably say I can do a clean job without screwing something up. Can someone tell me or show me how to do it. Will I need a new EGR gasket while im at it? Thanks

I've already read it. I have the PDF in my computer. I need to know how to safely remove the fuel rail to access the EGR. What do I need to take off and what do I need to leave on.

Default Gaskets needed?

I also have a CEL 12 and plan to clean the egr ports. Great job on that write up Hondadude! Question for me is if I will need new egr manifold gaskets and O rings for the injectors. There is no where to get them around where I live for a couple days and don't want to be stuck in the middle of the job if they tear or won't seal when I put it back together. Don't wan't to buy them either if I probably won't use them. It's a 94 EX with 170,000 miles. Also, is that chemtool spray okay for the O2 sensors? Thanks

What is different? The shop manual for the 94 says that an MIL with a DTC code 12 is for egr.

well it means the lift sensor isn't reading what the ECU expects.
It could be the lift sensor in the EGR valve or vacum not going to the EGR valve.
But there is no "low flow" code for OBD 1 cars, so plugged EGR ports will not throw a code 12.
