I have recently swapped a 98 gsr into a 99 civic cx. Im having a issue with it when it gets up to operating temp, the idle will fall to about 250rpm like its about to stall out but never does. When i come to a stop light it will start falling then when i pull out it will bog like there is no power until at least 3500rpms. I have cleaned the Iacv, tested the tps, replaced the map sensor, feplaced the fuel filter, new plugs, wires, and dizzy. The Pulsation dampener was replaced to. Timing is correct. We used the cx harness with a converison harness, computer is a virgin p72. There are no current or stored codes

I know this was long but thanks in advance.
