I have a 1999 Intrepid with a 3.2L and it was running fine when my daughter parked it, week later it acts like the battery is bad or bad connection. Tested battery, it’s ok, replaced connections, still nothing. Engine acts like it is either out of time or vapor locked, Have to hook battery charger to it to get it to spin over consistently. Pulled timing cover off and it was perfectly in time. What would make it act like it is out of time but confirmed its not?
