A few days ago I was out running errands and came out of one store to a dead battery. (wife and kids were in the car listening to radio with windows down for about 10 minutes while I ran in to grab 1 item).
I got a jump start and drove to a nearby auto parts store and picked up a new battery.
I noticed while driving to the store that when stopping the RPMs would drop to 500 and bounce up to 700 causing the car to shudder. After changing the battery I noticed that my auto up/down drivers window stopped working, but the regular up/down worked. I did a quick search and found how to do a reset of this by holding the button down and up for a few seconds.
After the new battery, the rough idle still remains when stopping at a light. This bouncing happens at 50% of lights and is not consistent. Sometimes the engine will idle perfectly at 600 RPM
If I turn off the A/C then there is no bouncing of the RPMs.
I did take the battery terminal connectors off and used a wire brush to clean them the best I could so that fresh metal was showing and not the corrosion build up that was there before.
There currently is not a CEL and I have not seen one pop up.
Thoughts? Is the A/C compressor failing? Is this normal? I seem to remember this happening on other hot summers once in awhile, but not every other time I stop.
FYI 2006 6MT TSX
Thanks for any input.
