Tested battery cells today... two good, three fair and one bad. sometimes it takes forever to catch on the turn over. this is intermittent but frustrating and somewhat embarrassing... 'aw, poor sap's car wont start'.
could it still be the battery? would adding acid or water to the bad cell revive it? (i've got some lying around) or... should i move on to plugs, alternator or ingnition? i have a fairly decent grasp on how an engine runs but I'm flat broke and cant take it to a shop. seems ridiculous anyway for something so simple.
side note: threw a P0420 code recently but dont have the funds for a new exhaust just yet. i dont think this is related but maybe there's an exhaust back up that is interfering with combustion? i dunno. this is where the 'fairly' comes in. just throwing ideas out there.
