hi I will be glad to help. The code that is causing your rough run is the p102.
P102 is for the mass air flow low frequency. Basic checks include looking for restrictions in air intake sysem,filter.etc... Look at the wiring connection at mass air flow sensor. Most likely you will replace the sensor to correct, but perform other checks first. The c codes are for the abs and traction system
