P0171 - Bank 1 system too lean.

P1133 - O2S insufficient switching bank 1 sensor 1

go to autozone and have them read your vehicles computer ,,,or take your battery cables off for 10 minutes then put them on and see if it resets itself ...most likely a code misread on your vehicle

take the wheel off,take the axle nut off,disconnect the spindle from the ball joint or joints, take the tie rod end out of the spindle and remove the spindle leaving the axle in the transmission. Now there is three bolts on the back of the spindle take theese out and beat the hub and bearing assy out. The new one wont be as hard to put in as the old one was to come out.

SOURCE: How do you remove the starter off a 2005 GMC Envoy

1st, remove the positive lead to the abttery. Next disconnect the wires from the starter one at a time. I recomment you wrap each with a layer of black electrical tape to protect them. After the wring is removed, remove the bolts to any brackets that are attached to the starter and the two large bolts holding the starter into the transmission housing. Remove the starter. Reverse order to install new starter. Test before your close the hood. It isn't very difficult. If you run into problems, ask me, and I will assist you.

SOURCE: how do you replace tailgate struts on a gmc 2006

There should just be metal clips on each end. Use a thin/standard screwdriver and pry out on the clips. They won't come off completey, but just pop out a little ways. Once they do, just pull and wiggle the strut and it should pop off the ball it's snapped on to. To install the new ones, just make sure the new clips are in the "out" position, snap the socket on to the ball and push in on the clip to secure it in place. Hope this helps.

SOURCE: hi i have a code

{: ) DTC P0506 Idle Speed Low
The usual cause is an excessive carbon build-up on the throttle body. If this is the case, I suggest you have your throttle body cleaned and perform an idle relearn procedure using a GM scan tool. The idle relearn or reset procedure is very important, otherwise this code may still remain even after a throttle body clean.
In a similar fashion, if the ECM/PCM (engine control module) of a high mileage vehicle is replaced and/or reprogrammed without performing the Throttle/Idle Learn procedure, the ECM/PCM may no longer compensate for existing carbon build up in the throttle body, causing it to return with a similar concern as well as DTCs P0121, P0506, and/or P0507.
There are other conditions that can also affect or reduce idle speed by increasing engine load like incorrect torque converter clutch (TCC) operation, accessories that require additional torque to operate, restricted exhaust, and mechanical conditions that limit engine speed.
