03 1500 5.7 Hemi misfire
When getting off the Highway truck started running like crap. Was about 5 mins from the house. When I got home hooked up the obt 2 and said “Random/Multiple Cylinder Misfire P0300. I pulled and changed all the plugs. Truck seems to be running on like 2 cylinders. I pulled the coils 1 by 1 and had spark on the coil but no cylinder fire. Checked fuel pressure on the rail and it’s at 48psi. Was wondering if anyone had this issue before. I went and unplugged all the coil packs 1 by 1 to see if the motor would sound different but I had 1-5 unplugged and it was still running the same once I unplugged coil 6 the truck stalled so that’s how I found out I was having nothing from 1-5
