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

cORRECT. tHIS CODE DOES DEALs With emmissions. P1400 deals with the EGR valve. In case u are not aware, EGR stands for Exhaust Gas Re-circulation. What really this valve does is that it re-cycles some of the exhaust gases into the cylinder for combustion. The EGR valve might be blocked or has malfunctioned. It is advised that this valve changed or consult with a mechanic who is knowledgeable about this technology. a malfunctioned/dis-abled EGR system will cause the car to fail an emissions test, and may cause the EGR passages in the cylinder head and intake manifold to become blocked with carbon deposits, necessitating extensive engine disassembly for cleaning. So it is advised that u repair this ASAP

both codes are for lean mixture ... bank one and bank two .....that usually means a vacuum leak in the air intake system ... there is a Y shapped boot off the throttle body that fails frequently .. look for a hole or tear or general deterioration ... there is a second boot after the MAF (mass air flow) sensor, that is another possibility ... any off the vacuum hoses you can see under the fancy cover plate could be leaking .. there is a "crank case breather diaphram" that can do the same ... you can test that by removing the oil filler cap slowly (running) ..there should be a sllight vacuum release ... if its a big vacuum whoosh and maybe engine stumbling then suspect the crank case breather diaphram ... finally you could have a bad MAF sensor but more likely the vacuum leak ... running with a lean mixture can eventually damage valves and valve seats ... i use a small rubber hose to my ear to find vacuum leaks (stethoscope) ...
