I'm usually on the Civic forum, but I have a friend that needs some help with his Integra.
He has a 98 Integra LS that runs great while it's cold, but as soon as it heats up it starts mis-firing. But it only mis-fires when the throttle is not open. So, if he backpedals, then it mis-fires, or if it's idling, then it mis-fires. I asked a Acura buddy of mine, and he said it was the main-relay, so I replaced that, but it still has the problem. I was thinking that it could be an O2 sensor, or a clogged CAT, but I'm wondering if anyone has any knowledge to drop here.

P.S. I seem to remember a post about this somewhere, but I couldn't find it using search, so if you know where it is, please direct me...

Thanks
