For a couple of days the car has had a misfire upon start up and idling , but once it has warmed up and i drive it, the car doesnt misfire ,but at stop lights you can tell there is a misfire(car shaking, rpms jump around)just this morning i replaced the plugs to see if that was the problem ran just fine till i shut the car off and started it again same issue i just pulled the codes and i know i got code 52 knock sensor and then i got code 14 coil and igniter /alarm, immobilizer
