I thought about checking to see if the rockers move for the first second or two on start up but I didn’t have a helper. When I have started I did notice that I thought it was firing on all 8 for a second but then I notice the misfire as soon as it starts to idle down a little. I would say the rockers probably move briefly on start up.
I have a brand new VLOM on hand now. I’m working on putting it in this afternoon. I’ll let you know how it goes.
Thanks for the help.
