Someone knowledgeable about car trouble? 1996 Honda Accord rough idle check engine light blinking?

It just started all of a sudden. Very rough idle, check engine light at first only blink after about 15 seconds at idle but now it doesn't blink at idle and instead only when at higher speed. Weird. I took it to mechanic he said low compression cylinder 3. I got synthetic oil change and put some Engine Restore in. Also replaced plugs they were pretty fouled. No change at all after 200 or so miles. Got codes ran at auto zone. Cylinder 3 and 5 misfiring, multi cylinder misfire, and VSS which I know about my speed sensor is shot. Easy fix tho. So my spark wires are new pretty much but I am wondering is it really the low compression doing this? I am thinking maybe cap and rotor or coil? My car used to smoke from burning oil but it stopped after this started. Yes I kept my eye on oil level. So what you think?
