It dies everytime I give it gas - 1985 Mazda RX-7

You ever change the fuel filter?

It may be a dying console (faulty electronics). Never heard of the compass dimming when you press the gas. Does it dim when you are in park and press the gas? If you give the console a gentle tap, does it brighten back up? Do other lights dim?

very unusual this but i havent any idea without having car in front of me ,these vehicles tend to pressurise the fuel tank and taking the cap off it releases the pressure ,very strang thats its affecting the starting though i would ask a local mechanic to have a look as from afar this is not something i can give an easy fix for .

most likely its the throttle body sludged up . clean the throttle body and butterfly . this will only help if there is an idling problem . ck for codes and ck freeze frame data for more help

Replace the idle speed control and check the TPS voltage

Could be a clogged fuel filter which is not allowing the fuel to flow properly

You may have dirty fuel injectors.

Hi, It sounds to me like your alternator is breaking down this will need to be tested and replaced if it is faulty.
