In all seriousness, +1 for stainless with these electroplated copper nuts. They torque down just fine, and stay put but taking them apart is much easier:

I think the ECU is hunting the idle to get the alternator to the correct RPM to run the car, charge the battery, heat your backside, etc. It also could be an alternator, but I'd probably do the previous items f...
