the engine temp starts lower then raises to 174. I reset the computer now it goes into closed loop still rich at idle but as soon as it goes into closed look it goes into fuel control also only goes into closed loop off idle.

Is this your daily driver? I can look at the bin and see what is going on as I'm unfamiliar with the 454 bins.
Are the IAC counts still all over the place?
Check your timing with a light and see what it's doing.
Double check all of your grounds to the engine and from the battery.

If it don't fit force it, if it don't force fit f&%@ it!
It's a driverish I ride a motorcycle daily and my wife's tahoe for most other things but I'm moving 1100 miles in a few weeks and need to do better than 6mpg unloaded. Plus I have alot of stuff I need a pick up for throughout the week. It's not that big of a deal if I can't drive it for a few days. After I reset the computer all things seem to be back to normal. Iac I got steady prior to reseting.
Oh timing is normal I set at 0 with the wire disconnected.
According to the bin scalar, closed loop enable temp is about 140 * f so you should be good there. I would seriously start double checking all ground and power connections, check the fuel system for kinks in the lines, fuel pressure would be nice to know as well.

Will it go into closed loop at idle?
I don't see anything in the scalars in the closed loop section that denotes closed loop idle but there are open loop idle items. We will assume at this point that bin is an open loop bin. Do you have the 4.10-4.56 gear set in your truck?

Yes it is 4.10 gears
