So this is my third deville. Crazy! I always end up with ones that have little annoying issues. Ha, anyways

Past few months the deville was idled up so high as soon as i turned it over the rpms shot up to the 5's. I'd have to throw it in drive quickly.
I literally burned out all 4 rotors and brakes twice in a week. This forum helped me so much, it ended up being the plenum and now she drives wonderful!
Only problem is is now i have a low idle.. sometimes she will stall out on me. I have the 3 infamous ABS, BRAKE, and traction lights on. Not sure if that has anything to do with it.

I ran the codes as follows...:

B0429 Temperature Control #3 Rear Circuit Range/Performance
B2463 Navigation CD Player - No Disk
C0660 Level Control Exhaust Valve Circuit Malfunction
P0741 TCC System Stuck Off
P1571 Traction Control Torque Request Circuit
P1644 Traction Control Delivered Torque Output Circuit
U1040 Loss of Class 2 Communications with ABS
U1000 Class 2 Communication Malfunction

I suspect these codes have a lot to do with the dash lights that are constantly on, but what about the low idle?

How can i get those lights off and what is the culprit of my low idle?

Any help is appreciated!

None of those codes are idle related. When was the TB last cleaned?

P0741 will keep the SES light on. You can clear it, but it will return. If you are not subjected to emissions testing it is far cheaper to ignore it and clear it. If you are subjected to emissions testing, you are screwed. You won't pass and the repair is expensive.

Maybe a year ago when i replaced it. I had originally thought that was the issue with the low and high idle.
Right now the Red BRAKE light is whats causing me to fail the inspection.
