The “54 WH93” code previously posted, was the error code supposedly detected by Honda to make a claim under the extended transmission warranty.
The transmission was replaced last Friday, and I was hoping the low RPM issue to go away. But it seams to be there. I only have a symptom, so I need possible causes to check them and troubleshot my car. I know some sensors can be checked by measuring voltage fluctuations and other DIY stuff.
Well if there's no DTC we can't help you with that. As far as the EGR, Honda has an 80k mile warranty on that. It's not that difficult to clean out yourself and a can of seafoam might do the trick.
