im sure this question has been asked before(although i couldn't find it) during idle my fc has problems keeping the rev's stable while electrical components are on, such as headlights,fans,radio, etc. all these seem to decrease the idle from stable to bumping up and down, not quite dying but close. is this an ecu issue? or something else? thanks

 

Poor grounding due to age is the largest contributor. You might also have a problem with the BAC valve, which supplies additional air when the engine is under load. For now, read up on adjusting your idle speed. If you bump it up a little, you won't nearly stall at idle.
