My 03 sedan has been a little sluggish on starting for awhile now, yesterday it almost did not turn over, so this morning I pulled out(the OEM battery and it was very low on H2O. With winter approaching I decided to drop in a new battery, besides the obvious quick starting and ECU reset… it feels like it running stronger. Is it possible or just my imagination?

 

possible

 

Very possible. If the battery voltage was low, almost everything suffers.
