Any input would be appreciated!

here's my case:
I was trying to change the dome light but seems i blown the fuse (15A). The car was on the "ON" mode.
I turned it "OFF" and then back to "ON" the RPM needle got to 10k and then retrurned back to "0".
I tried fire the car and it started just fine but the idle was not smooth some ups and downs.
Oh.. then i realised i have a blown fuse (the 15A) the one blown while i was changing the dome bulb.
FUSE CHANGED.
Then i tried to fire the engine.
DSC is blinking and TCS is on. I turned all to the right and then all to the left (someone is mentioning this in the forum) and both DSC lights gone off.
Then i reset the PCM (20 times brake in 8secs). I did this twice but it seems that it doesn't fix the idle issue.
The problem now is that while I REV when it gets back to idle it gets so low rpm which is causing the engine to cease.

I hope is something that you call "ECU relearn". There no mods either mechanical or electrical.

Some of the previous Mazda vehicles could blow the ECU with shorts associated with the dome light replacement. You might want to call a dealer that you trust and get it checked if you continue to have problems after an ECU reset.

Don't worry about it, the fuse you blew (bottom one in the footwell fusebox) is called the "room" fuse, powers the interior lights and the memory on the ECU.

You wiped out the fuel trim settings, so it just has to re-learn, then the idle should settle out.

It is indeed a fast learner (thank god)!

Just came home from a 6-7miles driving and the car's just perfect, as it is meant to be!

Thanks guys!

Sorry to revive an old thread but im having the same issue. Second time I seem to have blown the fuse that controls all my interior lights, radio, and interior locks. The "room fuse"; should replacing that also get my radio to go back on? I used to work at a dealer and when it happened last time they just replaced the fuse for me, I didnt really ask any questions as to which one.
