My 92 Legacy LS downloaded the following codes 13 and 32. I understand from the code chart they coincide with a cam angle sensor and the O2 sensor inoperative. I am thinking the O2 sensor would be the first one to fix since it may save me fuel in the long run.

Are they fixable at home without significant tool collections? or are they best left to mecanical type people? Comments and suggestions appreciated as always.

First thing you do when diagnosing things, especially when the computer spits out codes is to clear the codes, drive the car and then check the codes again to confirm that the problem still exists, and was not a computer sensor ghost.

A very good idea, I hate spending money I don't have, but the O2 sensor I would agree with since I have noticed a decrease in mileage and a few other symptoms that have been reported in previous posts too. But I will clear the codes this evening before I go to booking any appoointments at the shop. Thanks for the reminder.
