ok, so a while back, it had a little misfire out of nowhere. it only did it once for a long time. now its started doing it consistantly. hopefully its just something to do with the ingnition. maybe like the cap, rotor, wires or plugs. i was thinking that it could be. i have put a bunch of miles on those parts over a few years, not so much the plugs which have been changed out more frequently. anyways, looks like it has a good vacuum reading, so i dont think i have a low cylinder. but that is still possible. anyways, if i dont figure it out, leave me some suggestions. valve and ignition timing are correct. it kinda sounds like what my friends 302 was doing. but it was because of a crossed wire. my wires arent that great, one's boot is cut and may be causeing spark to jump. well, i'll be inspecting those parts tomorrow. probably will use a volt meter to check the resistance in the differnt parts. i dont have a problem replacing anything i've thought of. hopefully something easy. i was thinking if i dont find anything wrong, i might want to do a compression test.
