When the fuel trim is high teens or in the 20s then its the MAF that the problem. If fuel trim is normal, 2-5 then its the O2 sensor.
Buy "Electrickleen" at the parts store.
Remove the MAF sensor, WHILE COLD, and blast the wire inside with cleaner.
The "hotwire" gets gummed up and changes the resistance of the wire so you get a bad input to the ecu and it trys to lean out for a rich condition that doesnt exsist.When it cant adjust anymore it trips the po171 code.

Pg. 250 of your 2005 Owner's Manual shows the location of the Fuse Boxes. There is one under your hood on the driver's side and the other is under the dash just to the left of steering wheel. Pg 272, will show you how to replace the fuses. Pg. 286-287 gives a diagram and description of each fuse and what part of the electrical system it enables.
This portion of the electrical system correspondeds to the fuse in position 32 on pg. 287 of the manual.
Your going to have to get on your back with a flashlight and open up the fuse box under the dash by the steering wheel. The lid of the fuse box shows the positions of the fuse and their amperage rating. Like I said, replace the fuse in postion 32 (15 Amp). There is a spare 15 Amp fuse in the fuse box under the hood (easy to get to, see the diagrams in the owner's manual). There is also a fuse puller tool next to the spare fuses.

Under normal circumstances, the drum should slide right off once the wheel is removed.
If you have built up rust holding it on, there are two threaded holes near the center of the drum to aid in removal.
Insert two 12mm bolts into the holes and, while adding plenty of lubricant, turn the bolts in even amounts until they push the drum off.
Be sure to keep them lubed, as they will strip out easily if not.
If you have aftermarket drums without the holes or the screwholes are stripped out, smacking the face of the drum with a dead blow hammer will help free it up, but takes much longer for success.

po171 means the air fuel ratio is lean (not enough fuel) so you must check for anything that can do that a good example would be a vacuum leak that allows non metered air to enter the engine (more air same amount of fuel = lean mixture) or a clogged injector (same amount of air less fuel = lean mixture as well)
