Idle Concern?, 7AFE Idle Woes Options

[Hazmat]

Ok so I'm just now bringing myself to making a topic on this as its starting to show its ugly side again. I've got some weird idling problem going on as far as I can tell. Basically when the car is at normal operating temp and in neutral my idle will sometimes drop below 600 (probably like 580 or so) and everything will feel real rough and the car will Phsycially feel and sound real choppy like it wants to die but does not. This problem has shown its face on several occasions on random days (2 days in a row now) and the car will run crappy. Also want to say when it does do this I also notice that my gas pedal kinda loses its response. I feel like I have to mash down more on it than when its idling right below 1k.

Any information that could possibly point to my problem? The engine is rebuilt with about I would say 10k+ or so miles on it with new plugs/wires/distributor when the engine was rebuilt. I am currently left in a cloud of confusion over it all . I can also add any information I may have left out.

Thanks in advance

That definitely sounds like an alternator issue to me then, since it has to do with electrical load...

You may be right. I've always noticed that when I turn on the lights my idle will sit higher ( right below 1k where it should sit regardless of lights on or off right? ) and at night when I have my lights on and when I got to brake I can see my lights dim a little when I do it. All my internal lights will dim a little too when I use power windows aswell. Guess I should find a new alternator huh? Really had no idea an alternator had anything to do with engine idle.

I'm no expert at all, but it sounds like it. I have the same issue...using the power windows dims my interior and headlights. But it's not a huge issue, I'll probably upgrade when/if the alternator craps out.
