pulsing idle w/ cooling fans on

So my svx has issues lol first the cel comes on about 10-15 min of driving the code is 37 driver o2. I changed it but still get the same code. So i know many things can cause the code.
So i noticed the idle was low and a intermittent pulse so had Geln (rojorocket) adjust the Tps for me. Now the idle is up but the pulsing is still there and still same code :/
Thought it might be a injector so as it was running i unplugged each injector. The driver rear injector when unplugged it seemed to stop pulsing. Ran some cleaner thru it and a tank of chevron still no improvement.

Then thought it might be the coil. Changed it out with one i had and it didnt change... But as it was running i noticed something weird. When the cooling fans came on it started pulsing and then when they go off the pulsing stops. so now im stumped. Im trying to fix this so i can get it smoged.

Any ideas? Any help would be awesome!!

Thanks Izack

Btw its a 5 speed now if that changes anything.

Re: pulsing idel w/ cooling fans on

Also I just remember about a month ago I was driving it and all the dash lights came on as if it stalled or the alt wasnt working. But I was on the fwy so I kept driving and about 5 min later they all went off. And it has not done it again.
