I have a 2003 chrysler concorde lx 2.7l that i can't figure out the problem for the life of me. I have what id call a mist or jerking from what seems like the engine. I don't have any check engine lights or codes on. When i 1st heard it i thought it was possibly a misfire so i thought i'd have to change spark plugs and or ignition coils. I took it to more than 1 auto store to have the code scanner done anyways and what it says is "battery to transmission low voltage. Ive had the battery tested and it is good (12.6v). Alternator tested good as well. Battery terminals have been cleaned and tight. I get the same issue when im at idle or driving although it does seem to be a little worse at idle and with the ac on. Any ideas on what to check so i dont go wasting a bunch of money on things that arent broke. Could it be a map sensor
