ok, so my battery died this morning, dead as a doorknob. it was the OE battery and it lasted for 4 years so i wasn't too upset, i knew it was coming. anyway, i installed a new one and the car busted right up and proceeded to sputter dead. i fired it up again and instead of revving to 1500 like normal, it revved to about 900 then hovered there so i repeated again and same results. i figured fair enough cuz the engine was hot and all.
so anyway, i drove home and when i parked i noticed that the engine was idling slow, like 500 rpms. i kicked it up to about 1000 and let off the gas and it sputtered down to about 300 and then saved itself. it had never done this before. so i did some experimenting and every time i let the gas drop off from more than about 1000 rpms or so it would sputter down to 300 and then rev back up to about 500 or 600. it didn't seem to be running rough. any ideas?
