OK, plugs, wires, cap, rotor and EECIV injector cylinder balance test all come up clean on my sudden engine shake, but my timing magically shows 30 degrees BTDC (spout connector out), where I previously set it at 13. Is that a classic balancer separation symptom? It was new from Ford several years ago when it was an "SVO" GT40 crate motor, and it still looks like new. I guess finding true TDC with a cylinder stop is the next step? Were all 5.0 motor balancers interchangeable? This late-'90's SVO crate motor one came with a crank trigger setup, which I ignored for my '90 LX hatch. If it is in fact separated, will any 5.0 balancer work?
That is probably not even an issue and I am typing for nothin'.
