2 Questions 2003 NF Edition Trailblazer

[Murph8]

2003 North Face edition
116,000
Ok I'm only getting a 10.8-11.4 average mpg readout in the digital dash in all driving conditions highway and city. . . No fuel sensor codes. . .
Do have a code on coolant sensor turnin ce light on. Any ideas on the mileage thing? I haven't logged mileage and crossed actual mpg yet, but surely the digital readout aint that far off?

Another thing. . Got a inconsistant creaking noise in front end when rolling to stop. . . Sway links maybe? not a braking noise

One more thing haha when braking it doesnt stop smoothly it kind rocks back and forth. . . Maybe rotors surfaced unevenly during brake job?

Appreciate some input, thanks

city or highway 10.8-11.4
its always warmed up before it goes anywhere

got 4.2 6
116,000

noise is less noticeable when moving but its only over bumps and moreso when braking "my guess theres more force down on the front end when braking so the noise is louder because the front end is adjusting more over bumps under braking"

bought it in november with new brakes and fresh surfaced rotors
fresh tuneup and service

not a brake noise and pads are 99%
I think when they surfaced rotore they machined off a little bit causing the grab and let go feeling. . . Brakes stop the car just like they're supposed to they grab good there's just a shimmy. . .


The noise the front end is making is basically the same noise an old mattress makes when a little kid jumps on it. . . I'm just trying to put off dealing with it. . . . I need to just get the dang thing up in the air and check out the suspension. . . shocks seem good ya know they rebound and compress ok front end isnt loose i just cant picture it being anything but sway links. . . I appreciate your input i'm just gonna have to get off my butt and do some lookin

Grab and let go is not good.
Is ABS kicking in?
While you have it up in air take a good look at pads and rotors and calipers.

Good Ac delco parts use with tune up?
Any codes or check engine lights?
