I've been reading old posts about potential of an EGR delete for 98-02 Honda Accords and the consensus seems to indicate that it can't be done without a tune of some sort.

Anyone successfully installed block off plates for the EGR for the F23A1 engine?

 

So why are you trying to delete the EGR valve?

 

Exactly. In my case I was mainly trying to get it to work correctly. I ended up replacing a new valve with another new valve to get it work right. I still believe you can get a bad new part.

 

I've been hearing about having to clean the EGR and intake manifold.

 

It would probably be easier to just remove the upper part of the intake manifold and clean out the port on the lower intake manifold.

 

Yes, that's how I did it on my wife's 2000 2.3 L 4 cylinder. It's just inside the throttle body end that gets coked up. From what I understand, you should only need to do this once in the life time of the car. But if you own it a long time, maybe twice.
Just a heads up warning, you have to disconnect the small coolant hoses on the back side of the plenum (firewall side) on the IAC to get the upper plenum off (worst part of the job). I also unbolted the bracket for the throttle and cruise control cables, so I didn't mess with their adjustments. What you'll see is a chunk of carbon about 1" by 1/2" thick by 1" long that is closing off the EGR port. I knocked that chunk out, and also ran a section of steel welding wire thru it to the valve (had the valve off). Then put it all back together. It's been fine for over 5 years now. I did have to replace a new valve with another new valve, due to getting a defective part. Oh, and the Honda dealership gets 300 labor for that job, plus the cost of the valve. Well at least 5 years ago they did, the price has probably gone up since then too.

 

Sheesh, $300? That's crazy. It took me 10 minutes to get my old egr valve off my f23a1 accord last night. I hope that's with cleaning all the passages too
