the car has about about 185,000 mile's i have no record of any 02 senser's or cc being replaced.
The car has really bad gas mileage, bog's down going uphill, can't get the rpm past 2500. What should i check first? 02 sensor's or CC? Does the v70 t5 have issues with 02 sensor's or CC?


Thanks very much

What OBDII codes are you getting?

There are no codes or check engine light. I have ordered a new front 02 senser well see what that does.
