Coil plugs wires all new. I change wires 1 for 1 about 4 months ago. As for compression well I'd have to research I'll assume you mean piston compression. Everything vacuum wise has been replaced or checked many times.Try checking compression if you have you think you have confident you don't have a vacuum leak or ignition coil and or plugs and wires. Also make sure you ran the wires properly to the right place. Easy to mess those up.
