MIL P0300 ans P0172 :(

[njaremka]

so, my car has started to run very poorly, making me very sad :( then, the other day, my MIL illuminated, and gave me the codes P0300 and P0172. I have no idea where to start. i have new coil packs, wires, and plugs - i tried cleaning the MAF - nothing. the car has a very erratic idle, and sometimes has a hesitation from take-off.

any thoughts, before i take the car to the dealer for diagnostics?

no idea what the code is..if you've been driving it a lot during winter and snow it might have just fucked something small... hopefully
