i know this topic has been beat to death, but after a week of searching no answers. right now i have a 97 accord, locash obd2 to 1 adapter, p13 ecu. all the wiring is good, no codes except for the random code 12. right now i have t he stock accord egr on the h22, with the vac line (16) unplugged. if you plug the vac line in the car idles like it has huge cams. which is why i leave it unplugged, and i assume this unplugged vac line is causing the CEL.

so what did you guys do to remedy this? do i have to use the prelude egr? is there something i dont know about? is swapping pins a6 and a11 only for obd1 accords?
