Engine misfire
So I have my 96 blazer 4.3l v6 well a month or so ago it started misfiring during alleceration. it misses most under a 25-50 percent throttle. if I putt up to 25 it usually wont miss or if I get into the throttle alot. and as far as I can tell driving at any consistent speed it wont miss either, it starts right up everytime, and idle seems normal... it has not thrown a single code. during a scanner test drive it showed that it was not just one cylinder. they all miss and there is no pattern to which ones miss. I replaced the cap rotor wires and plugs recently. I am thinking ignition module but I am not really sure. I dont think it would be the coil...I figured they either work or they dont work...anyone have any ideas?

These things are real fussy with secondary ignition parts. What brand of cap, rotor, wires and plugs did you install?
