Misfire after jumpstart
My mom's car (Elantra) battery was dead so I jump started with my car (Lexus is300 2001). I did not drive my car that following day until the next day. On the next day I started up the Lexus I found out the battery was dead, no cranks, nothing. After jump starting my car, the car ran fine for 5 mins. It then started bogging down and hesitating with all the dash lights freaking out. I parked the car on the curve and it turned out the battery was dead again. I proceeded to jump start it again it but it hesitated and died. I installed a newer battery which started the car however there is now a multiple cylinder misfire. The car throws p0300, p0302, p0303, and p0306.
-At first, I thought it was an alternator problem but it was the battery.
-what could be the problem for the multiple misfires.
-The car had multiple misfires before but it was fixed by just restarting the car/ clearing the codes
