I unplugged the idle air bypass

or just cut the mechanical connection, though it would be nice if I could put things back to stock with ease.
I'll mess with that after coffee.

You can always choke the valve by placing a gasket with a smaller hole between the IACV and manifold. That will tame things down.

That probably is the best solution, since the IACV will still work, just with less intensity.

No CEL in the truck. I still need to try driving the car with it unplugged. I unplugged it and then started it up and it slowly built revs until I shut it down. Not sure why. I will try it again and drive it.

The truck works great! It almost dies on cold start but a tap of gas will cure that. Not much power on cold cylinders. I REALLY don't like those 2000 rpm on COLD winter starts. It will be getting a switch/rheostat this fall.

The car revs to 3500 rpm to warm up when it is -30° or colder!!!!! NOT GOOD!!!! I don't like to see those kinds of rpm on a cold engine with no oil flow.

Okay, so with a little googling I've found that my car has a CEL code for the IAB, but the IAB has some manual adjustments... I've got some playing to do, I just wish it wasn't so darn hot and sticky out today...

I was looking at my throttle body and I have an adjusting screw for the closed-throttle position. Maybe give it a hair turn?

Turning it up a hair won't hurt. As long as it idles no higher than 850 or so in neutral when fully warm, you're fine.

I will probably turn it up a hair then.
