SOURCE: service engine light
Code P0102 indicates MAF(Mass Air Flow) sensor circuit, low frequency detected
Code P0300 indicates Random Cylider miss fire, meaning missfire in more than one cylinder
The misfire could be a result of the mas air flow sensor being faulty.
Hope this helps for now
Let me know what size motor and if it's 2wd or 4wd and I can get detailed instructions for replacing

p0171 is system to lean (bank 1 ). anyways it is either going to be a vacuum leak causing the system to go lean from unmonitored air, . check for vacuum leaks first. One way to help you diagnose is start the engine and listen for any whistling noise. also make sure air filter is not dirty.
