97' spyder weired battery prob...
 

hey all! about a week ago i bought a 97 spyder from a lot has about 130k on it had two codes on it one for the down stream o2 sensor and one for the cam position sensor... its choked and died a few times since iv had it and just last night went to a friends house 3-4 hours later when i went to leave the battery was dead and i dont recall leaving lights on because it was daylight... i jumped it, it started, but turning the lights on almost killed it. right as i got home the engine started choking and died. what was weird was that the lights were dim the whole time even putting on the blinker caused the rpms to drop but no battery light and the engine was choking as if it wasnt getting a spark... any ideas?
