P0401 EGR Valve Port Cleaning
This is my DIY for clearing the CEL code P0401 (EGR Insufficient Flow) on a
98 Honda Prelude.
In cars with OBD2 if the EGR valve is restricted by carbon deposits it will
detect that and throw a CEL. To get rid of that CEL you must clean out the
carbon to allow flow.
After combustion occurs within the engine it creates Exhaust. Gas from the Exhaust straight from the engine is very bad for
the air. The EGR valve recaptures that Exhaust and runs it through the combustion
process again, which lowers the temperature of the fumes (Exhaust gas) and lowers the amount of pollution
exiting into the atmosphere.
If you don't fix it you won't pass SMOG in California. You may experience
rough idling and poor acceleration.
Get your "EGR port plugs" from Honda. They will have it.
Removing the injectors are important to allow clearance to the port plugs.
When you pull out the injectors you might as well clean them since they are
Slide hammers make pulling the port plugs out easily.
Drill with a bit the size of your tap. Drilling halfway through the port
plug to should be enough distance to fully grab the port with the slide
If after you clean your ports and valve the CEL has not been cleared, you
EGR valve maybe faulty and needs to be replaced.

How To Clean The EGR Valve On A GMC Safari Vortec V6 Engine
Here is how to clean the EGR (Exhaust
gas recirculation) valve on a GMC Safari Vortec V6 engine. If your engine
started running really rough all of a sudden, your EGR valve may be stuck
open. It's easy to remove and clean up. It is a good idea to install an
EGR valve gasket with a filter in it to prevent future carbon buildup.
Here is a link to a video I made showing the gasket:

and "crank, no start" situations as they are treated differently. This
video covers what I do when confronted with a 'no crank, no start'
situation and in this case it's a worst case scenario so be sure to watch
