buick park ave sounds like its missing out PLEASE HELP NEW STARTER PLUGS WIRES COILPACK IGNITION MODULE STILL MISSING OUT

I have a similar intermittent rough idle. I have heard it might be the cam position sensor. Anyone else have any input?

Honestly, it could be a number of things. And a number of things in which I replaced/repaired on mine, but it still persists when it wants to, I've just come to accept it with my '87. One mement it's fine, the next a little bumpy.
