Interesting. Maybe a coincidence, but I pulled the EGR manifold and it was completely clogged with soot. Cleaned it up real well, reinstalled and the CEL has not come back. Car idles better too.

 

Interesting. Maybe a coincidence, because the EGR valve........ DOES NOT OPERATE at idle speed.

 

If the EGR opens or leaks a little at idle (when it's supposed to be closed), it'll mess up the idle, right?

 

Yeah, I don't get it either. My son commented that it has better pickup. He would know better than me, since I seldom put my foot in it. Anyway, Hondadude, thanks for posting those instructions. Light out, running better.

 

ohhh god you couldn’t have said it ANY better!

 

Yes Jim that is correct;
It used to be the easy check for port plugging on the old style EGR valve, stick your finger under the cap and push up the pintle and the car would stall at idle if the ports are clear.
But nowadays we have to get all fancy and hookup the scan tool then go thru the menus to "command" the ECU to open the EGR.....and then you get to clear all the codes you trip by doing that simple test.
What used to be a 1 minute tool free test is now a "super technology" chore that takes 15 minutes.
Isn't progress just flippin great?

 

Progress....
Used to be able to check tire pressures in 90 seconds with a little gauge you can buy from any store. Now you need TPMS sensors at each wheel ($75 each) because a bunch of SUV drivers didn't want to bother checking their tire pressures. Much easier to call a lawyer after you crash.
Progress is just flippin GREAT!

 

is it different to clean a 94 accord non-vtec or is it the same???????

 

Its the same.

 

Hondadude, your DIY with pictures was just what I was looking for, thanks.

Can the injector o-rings and the gasket under the cover be reused, or do I need to go pick some up before I start?
