I own a 2005 pontiac grand prix 3.8l series 3 and while im driving my car just shuts down just the motor i got power inside my windows and radio and all and the car says starting disabled due to throttle position control then it says engine power low and i have also noticed that it seems to happen more in the morning on my way to work like in colder temps or dewy temp also noticed that transmission shifts a little different..i have had it put on codes got back P0601,P0606,U0107

Seems that the codes deal with a power problem to the cars computer.
I would remove the air box and take the PCM out and check for any damaged wires or if the connections have corrosion.
Make sure to unhook the battery before you do anything with cleaning or taking the connectors off.
Thats just something to check here, but a likely cause is that the PCM has failed.

I removed it today and it looked clean and I didn't notice any wire damage. If I order a used one is it possible it will work?

I put the used ecm in. Had to do a security relearn on the key. Now it's running good.

Good to hear.
A failed PCM is pretty rare.
