1984 240 injected. 200

SO,

how do i know what is causing my rough start, bad idle, running rich problem.

i had response from Mass Air when unplugged, o2 sensor, and the injectors seemt o have an affect wehn i unplug them one by one. The one closest to the cabin and the one closest to the nose when unplugged didnt do much to the idle.

Also i have a slow loss of battery power, im thinking bad connections to the alternator, or bad alternator.

Any thoughts, and if any, could you be detailed in where i would find these things to check, and HOW to do it.

this weekend i will be cleaning my idle motor and throttle out.
