wow great info thank you. now for my 86 22re what should my timing advance be at what rpm? and if it is out of range would i be looking to pickup, ecm, tps? would ignition module have any relativity to an out of spec timing advance?

You have only one specification when it comes to ignition timing advance. That would be the specified initial(or base) ignition timing. Which is to be set to 5° BTDC @ idle(800 rpm) with the T and E1 check connectors jumped(short circuited). Beyond which there are no other specifications or recommended procedures for checking the ignition timing advance(such as at any other rpm above/below 800).
BTW, what do you mean by "ignition module"?

when i said ignition module i meant the igniter. the reason i am interested in the ESA is because i do not believe it is accurate. when timing i find that i can go from a 5 BTDC to what would probably be around a 25 some advance as soon as i hit the throttle at all. the issue i am having with my rig is that i am getting bad mileage and power and while increasing the rpm at around 2 it develops a horrible misfire and causes the entire vehicle to shake. i bounce most of my ideas as of what is wrong with my truck at work and stump techs that have been turning wrenches longer than i have been alive. i just don't know where to go next. this has really turned into a head scratcher for me..

It advances timing pretty rapidly. I forget, but mine jumps 15 degrees or so, right off throttle. If it's missfiring, try pulling plug wires off while its misbehaving, see which one doesn't change anything. Do plugs and related bits recently? All your injectors healthy?
