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?
