Howdy, new hemi-owner with 2012 1500 sport, 200k. Have a misfire and cylinder 5. Has all new plugs and coils. I already swapped coils and plugs and injectors. While checking pulse to coil with test light, other cylinders had steady blink blink blink blink. Cylinder 5 had blink dim-blink, blink dim-blink. Are these trucks known for having PCM issues not sending a steady pulse to coils? Or possibly a ground? My next step is to remove valve cover but for some reason I feel this is electrical. Any help appreciated, thanks!
