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.
code p0300 refers to random/multiple misfires--misfire detected===causes--spark plug/sHT leads--injectors--ignition coil/s---low compression---wiring
code p0171 refers to system too lean, bvank 1===causes--intake/exhaust leak--AIR system--fuel pressure/pump---MAF/VAF sensors---injectors---HO2S sensor
The common thread is fuel so have a pressure test done on the fuel system to check for pump and / or faulty pressure regulator, then progress to injectors.
P0171 and P0174 are telling you that each cylinder bank is running too
lean. P0300 is telling you there is a misfire, possibly caused by the
other codes. This is why the engine is running rough.

P0300 Random/Multiple Cylinder Misfire Detected P0171 System too Lean (Bank 1) - Read Our Article On Oxygen Sensor Codes For Help With This Generic Check Engine Light Code
i could only find the 2 codes for you
try here www.engine-light-help.com
what kind of shape are your plug wires in ?
HI
P0300 is multiple misfires.
P0171 is lean burn on left bank 1 means drivers side
02 sensor is faulty. Your vehicle is over fuelling that is why your are getting P0300 code and the rotten egg smell. Good idea is to replace both 02 sensors.
what are the new codes clearing / resetting doesnt fix the problem the p0171 code has about ten different causes just changing or cleaning the sensor may not have been your problem P0171 System Too Lean Bank 1 rescan and get all codes then look up each one most sites have causes and solutions for obd ll trouble codes
