EGR code 12 after swap

[rdeal317]

Tell me if I am heading down the wrong path here:

Code 12 after the H22 swap and a little bit of stumbling here and there. '91 Accord, P13, previous owner of the H22 just used a block-off plate when it was installed in the Civic. I decided to transfer the EGR from my F22 to the H22 since I used my stock harness and I wanted to attain something I've yet to experience in any of my swapped Hondas, NO MILs.

The system that worked perfectly on the car before the swap is now seeing insufficient lift, so I'm thinking that with the block-off plate on there for a couple of years the plumbing is jammed full of carbon that had nowhere to go. The inlet side of the blockoff plate was black, possibly strengthening this theory.

From my research on the EGR system that my P13 originally ran and the system in the Accord, the voltage, vacuum, and signals are the same - they just have different component locations (except for the EGR valve/diaphragm thing). Or am I missing something here that the P13 wants to see and the Accord never had?

You should be ok with the F22A EGR. Try pouring some seafoam into the egr hole and let it sit for a while to see if it will clean some of that crap out. If not, you might want to do the EGR port cleaning which is described in a thread in the DIY forum.
