Does anyone have a scan tool I can borrow?

Pulled them today. It has 3 codes:

121= Maf sensor
113= Heated o2 sensor-max enrichment (It says this is only only on 94+ cars :gotme:)
221= Heated o2 sensor

Hopefully this is all thats wrong with it. I dont want to have to drive the fbod in the winter :tdown:
