I"m going to bring this thread back to life by adding that I have a 2000 honda CRV which is developing this same problem. I honestly cant recall how long ago it started. The thermostat was stuck open and the engine was running very cold for the last few months and I almost forgot about the issue. I just replaced the thermostat and the flare is back worse than ever. Only happens between 2-3 gears and only with light throttle application. Only happens when engine is at normal operating temperature. I've got 199,000 miles on this car and I'd like to keep it going.
If I may ask why didn't you try just replacing the PCM if you suspect that is the cause? I am an electrical engineer by trade but I don't know much about fixing cars.
