#2 & #4 cylinders won't fire at an idle Hi swapped a 2002 5.3l into my 1970 c10 and 2 and 4 cylinders don't fire at an idle. Check compression and running compression both are good. Got spark to the plugs. Good fuel pressure. Changed o2 sensors and computer. Moved coils and injectors around but still same 2 cylinders won't fire at an idle. Any help or thoughts. Going out of things to check and replace.
Thanks
