p0102 is your Mass Air Flow device.
p0113 is "air intake temperature" sensor voltage too high.
p0171 is "engine running too lean"
p0300 is "random misfire"

You can pretty much ignore your p0113, p0171 may be caused by a bad MAF, and p0300 may be caused by your p0171.

the actual indication for your MAF is that the voltage getting to the computer from the MAF is too low. It could be a bad MAF, or bad wire between the MAF and the computer.

Needs to go to a repair shop, to be road tested with scan tool,
& the codes properly diagnosed,component tested & the vehicle
repaired as required

You can Google your codes

Type: OBD & the code

OBD PO300

P0300 Means randome miss fires detected; Cause is you may need a tune up.Or you just drove over one very bumppy surface. P0171 is caused by the unburnt fuel from the misfire.

Check for vacuum leaks to start. Then check the evap system. I just replaced a evap vent solenoid on a suburban with the same codes. fixed the problem.

Change the Mass Air Flow sensor.Or the the Volume Air flow sensor.Also replace the ( IAC ) Idle Air Control. There is no code P1518 are you sure they wrote it down for you correctly? I just had my Library of codes updated last week and it is not on the list. After all repairs are made make sure you have the Diagnostic Trouble Codes Erased from the on board computers memory. This will reset the check engine light and keep it from comming on again for thoes codes.If it does come on again and it relays more DTC you can ask me for further help through the Reply Window. Good Luck and have a good XMASS.

hi i have a code p0001, what do that mean and how can i fixed or where that part is located.

A P0300 code is a random cylinder misfire code and could be caused by a bad plug, plug wire, or fuel injector. The P0171 is bank one o2 sensor is reading lean w/ both of these combined could mean a vacumm leak.. Hope this helps.
