idle problem fixed, electrical problems now?

[spectr019]

As my subject says, I fixed my idle surge. It was the ISC. I put a new one on and had a shop down the street re-adjust my BISS. My car idles at 750 +/- 50 pretty perfectly, however it seems like it's struggling electrically. The CEL, SRS, and ABS lights on my cluster dim in and out, and the car shakes a bit constantly, and the engine doesn't sound like it's operating smoothly. However, if I give it even just 1% throttle, the shaking stops and everything is smooth. I've never had this problem before, and especially since I have an Apex super ground stabalizer, I've never had any electrical problems. Should I bring the BISS out just a tad and raise the idle a bit? Alternator going bad? Battery dying? Any suggestions? I tried searching, but nothing about this electrical problem was to be found. Thanks yall.

I would check to see what the alternator is charging at. You can use a multimeter on your battery posts at idle, if the alternator is in good shape I do believe it should read somewhere around 14v +/- .5.

Sounds like your timing is off at the low rpm. If you don't have a datalogger to verify your timing then just bump up the idle a little. I run mine around 950 warm.
