sensor problems?

Big problems, A/C quit working, a month later, car wants to die when accelerator is pushed, especially in morning. These trouble codes came up from Autozone, 0102 = mass air flow, 0135 & 0141 = 02 sensors?, 0172 = system too rich, 1652 = IAC monitor. Are all these sensors bad or could one bad one cause the other codes to show up. Have to do work myself, shops charge more than I have. Car has 180k+ miles. Need help soon, e-mail directly crazylori@ec.rr.com or please reply if any suggestions. Thanks

The O2 sensors and MAF sensor being bad will definitely mess with your mixture, which explains the 0172. IAC could just be bad by itself, but all of these sensors are easy enough for the home mechanic to replace. Just grab a slotted socket for the O2 sensor and a Haynes manual, the sensors in question, and you're set to go.

Thanks for the advice. I'll give this a try.
