2001 Toyota Corolla • 135,000 miles

I had my car change the oxigen sensor (bank 1 ) yesterday. It was working fine in the morning but just drove it and I can get more than 30 or less in milage. At time the car kept pulling back and reduce my speed even though I kept putting the gas. Also lately my car has been burning more oil than usual. My car was not yet due for oil change (2 more weeks) and the oil was completly gone. I had to put more until I can get to the near oil change store. My car is a toyota corrolla 2001 about 135,000

Scan for codes and check fuel pressure with a gauge first. Try replacing pcv valve for the oil problem then have coolant system pressure checked for a blown head gasket.
