93 civic ex its horribly almost every time I give it gas, when its in park I can rev it and it won't miss, only when I'm driving and its underload it begins to miss. I have another civic I been swapping parts from to see if it helps any. I have put new plugs, vss sensor, coil, rotary button, and cap. Its not throwing any cel, and when I put the distrubor cap on it burnt the middle part of it up. So I was going to check timing to see if it was correct, how hard is it to check timing without a timing light? Like taking off the valve and timing cover to see if the marks line up.
