Another odd idle problem
This I find very odd. Here's the rundown. Newly rebuilt motor, new alternator, new battery cables. Battery terminals cleaned. Idle at 850-900. When I put the heater on the idle will change about 100 rpm. Is this normal? I think the headlights dim as well when I do this. Also, I don't think its a water pump issue since I have a problem with the heater control valve and that's open full time until I fix the cable that runs to it.
I am thinking maybe the blower motor is worn out drawing more power than it should be causing more of a strain on the alternator resulting in a lower Engine RPM?
This I believe did this before the rebuild as well.

gonna have to help me out here and explain a bit, still kinda a newbie at these toyotas.
somehow I wound up with a parallel thread and the blower resistor came to mind as well. ( I guess I am a reposter too haha )

It is a twofold problem.
One, the alternator is so weak that it cannot support many accessories. Two, the cables are fairly small to start. This is why everyone suggests the big 3 upgrade. A friend I helped with his 92 4Runner did the Big 3, and installed an upgraded alternator, and never had this problem again. Even after running a TON of electrical accessories.

2 gauge battery cables and a brand new alternator. I think its the blower motor drawing too much. I will get a chance to look at this tommorow and post up, if I don't freeze to death before then lol
