I have a '92 Accord that stumbles/ shuts off when I give it gas. I keep hearing that it's clogged EGR ports. I have cleaned the EGR valve but I guess that's not enough.

Does anyone know how to clean the actual EGR ports, or even what they are? I keep finding links to some .pdf file on how to do it, but the links don't work. Thanks for the help!

Stumble and 'shuts off' are 2 different animals, To clear the EGR ports on that engine requires drilling with a long shank drill bit and threading the drilled holes to insert a screw so you can use a slide hammer to get the port plugs out.
A good test for EGR port plugged up, is to 'power brake' the car, warmed up, to around 1700 rpms to see if there is a stumble in that range.

I guess I'll give that a shot.

Like I said, so far I cleaned the EGR valve with brake fluid, but apparently it's a little more involved than that. I don't even know where, or what the EGR ports are, or what these plugs are....

Plugged ports will not cause this problem. The only way the EGR can cause the car to stumble is if the valve is not seating properly and is allowing exhaust to pass to the intake at lower RPM's. If the ports are clogged, no gasses would be getting through. That's why the test for clogged ports is to pull a vaccum on the EGR at idle and see if it stumbles. If it doesn't stumble, the ports are clogged. If the EGR was cleaned properly it should be seating properly. The best way to clean the pintle and seat on the EGR is to pull a vaccum on the valve with a large syringe or hand vaccum pump and polish off the pintle with 0000 steel wool with a twisting motion. Spray it out with brake or choke cleaner and it will shine like new. Release the vaccum and try to blow through the pintle to see if it is seated. If the problem persist after this cleaning, your problem is not EGR related although your ports may indeed be clogged and in need of cleaning.
