So, last week i had to block it off. My pintle wasnt coming all the way down, which was causing rough idle and other random shit. odd enough i didnt get a SES light when i coke-canned it. So, i went to the wrecker, and i found one and cleaned it up right there. It seemed ok. The pintle came all the way down, but im still noticing some MINOR jerking when the car starts to go, if i floor it, im fine, but if i baby it, i notice some very minor jerks. Is the EGR still screwed, or is there something else that could cause that?

Clogged EGR service ports will lead to roughness (either crusing or accel) @ part to light throttle @ 1800 to 2500 RPM. -
x2, clean those right up and you'll solve your problem... it solved mineOriginally posted by Granite CB7 View Post

EGR will affect it at low cruising speeds. Your "minor jerking" when you "baby" it could be with your spark plugs being old/burned up... also if your tube seals are leaking, you'll get some oil build up on the spark plug making it harder to fire.Comment

I cant see how the ports would cause hesitation. Its not like your cleaning the rest of the line all the way down. Im not able to buy the port covers however... Whats the part number for those, or should i just tap it for 10MM bolts?90 Accord EX F22a1 Auto R.I.P.

here's the part number for the plugs, P/N 17199-PT3-AHM, i think they're universal for hondas with an EGR system...
they're not as solid as the originally equipped, they warp easy when banging them in, so get a lot. I think you need 7-8 plugs, i got like 12 plugs and messed up atleast 3. They're only like .30 each.

I remember There is a removable plug on sale somewhere so you don't have to drill for future service. Anyone know where is that Removable EGR port plugs?Comment

The reason why the motor will feel rough when the ports are clogged is b/c all the recirc'd exhaust gases will be going into 1 cylinder instead of 4. Basically over time, the ports will fill up and clog, 1 by 1, until there is only 1 open port. The orig. OEM plugs are brass (the 6 on top and the larger 7th) and the newer Honda ones are stamped steel, very cheap IMO.
Regarding the thread in plugs for future use, the 7th larger port on the far right side is already the correct size (29/64") for a 1/2" pipe plug or set screw. I enlarged the 6 ports to 29/64" then tapped them to 1/2"-20 and used 7 1/2"-20 set screws, worked really well. This was on a spare set of runners, I would hesistate to do this while the runners are on the motor b/c of metal shavings!!!Comment
