P-0102 and P-0113 are mass air flow and intake air temp codes, the P-0136 is an Oxygen sensor code. Before you do anything, check for debris in the Mass Air Flow Sensor, it's small black box with electrical wiring connector that is screwed into the intake air tube, between the air box and the intake manifold. Undo the screws, remove the sensor, and, with a flashlight, and look down inside it for debeis, or broken wires inside it. If it's dirty, it could throw a P-0136...Comment back on what you find; hope this helps, and thanks for choosing FixYa!

Check the voltage of battery with voltmeter.. It is sometimes possible that if voltage of battery drops and jump start is needed, your computer will only charge to the last voltage that was recognized which would be when jumped...Try and charge the battery if possible I would actually suggest that you have your battery tested at local auto parts store and if it is presumed in good condition ,let them charge for you to max capacity . If battery has been tested and labeled as no good replace if necessary... Oh, and first thing you should do is make sure your positive and negative battery connections are clean and tight...if this didnt fix problem please give more info on what was found when advice above was followed...Good Luck!!!!

The throttle body needs cleaning. It has some carbon build up, and when the battery went dead the computer lost its learned values, one of which is base throttle position. Now its reset back to factory specs, not accounting for a dirty throttle body. Seen it a million times

If it back fired it is possible the timing jump a tooth. If so, you'll have to have the timing sprockets placed back into the proper spots. Have your mechanic do this if it's needed. But in any case have the timing check first.
