hello. I have recently swapped a f20b sir in my 97 accord coupe. even though the engine is obd2, it has been wired with my original obd1 harness. As a result. i had to change my upper intake manifold plenum for the H22 so that the iac could be plugged into my obd1 harness. However, I am using the iac valve from my original engine, f20b sohc non vtec. Even though the air ports are the same in its shape and size, the valve itself is different. Instead of the water lines being on the bottom when it is installed, it is at the top when the sohc iac is installed on the h22 intake. I have been getting a low, rough idle and some dead spots so I wanted to know if the iac valve is functioning properly. Thanks in advance.
