2G check engine light codes..need help

[eclipsegst24]

My check engine light has been on for about two months now, came on right after i put my intake on. I just got around to getting the codes pulled.

volume air flow sensor(P0100)
barometric pressure sensor(P0105)
intake air temp sensor(P0110)
idle control system(P0505)

I have done a little research by searching forums and have found that these all my be linked to the same problem, either the maf is bad, ecu, or the wiring, and something about a tps. I may have broke something or messed up something when i put on the intake. I was also having a inconsistant idle for a couple of weeks but it has stopped. I am looking for any advice or input from you guys about these codes, and what the problem may be and what i can do to correct this, and get ride of these codes.

reset the ecu ... make sure the harness is plugged back into the MAS and go drive it around for a few miles and let it idle for a while too. Then drive it normal and see if the codes come back.

Is there anther way of reseting the ecu, the only way i know is to disconnect the battery for a little bit.
