Voltage Fluctuation on Start-Up
When truck is first started, cold or warm, voltage is just under 12 volts and can drop to 10. After about half a minute it goes to normal at around 13+. Idle has fluctuation with volts too. But idle speed is different, it drops 50 or so RPM just like when the AC kicks on, only the AC is off. I just replaced the CPS.
Any Ideas?

Yes, after running for a few minutes. I never seem to have any time to sit and wait until the fluctuation stops,, but I guess it stops while driving. I do wait for the "wait" light to go out before starting.
