Hey guys. I have a 2000 Accord 4cyl 5spd. I have a chipped P28 ecu (F23 basemap) along with the OBD2-OBD1 conversion harness. I hooked it all up today and the idle fluctuates between 1200-1500 rpm. Now, I drove the car and it's very "bucky" when I let off the gas similar to before you stall, but it only bucks once. When I floored it, at about 3500 rpm, the car almost stops and feels like it's struggling and doesn't increase rpm. Any ideas? The CEL is also on, but only when I turn the car on. If the ignition is ON, the light is off, but when I start the car it comes on.

Now, I read on AccordinglyDone something about switching pins A6 and A11 on the harness? Since it's an Accord harness and a Civic ECU, should I try that?

Yup switch em. Do a search, it should be in there.

 

Thank you. I tried searching but it didn't come up. I'll try to search for a P28 pin diagram. Thanks again.

1 problem I see is that in the A11 slot there is no wire. I was under the impression I would have to switch 2 wires. Do I need to put the A6 wire into the A11 spot?

And supposedly the P28 doesn't see an EGR valve since the Civic's didn't have one. I tried unplugging the sensor, still idles the same. I'm stuck. I don't know what else to do. Especially because the wires feel like they don't come out of the harness. And, being that there's no A11 wire in my harness, I'm at a loss for the whole "A6 and A11" switch. Anyone please.
