My car, a 2004 Dodge Stratus 2.4L DOHC, is losing power when I accelerate. The rpms go up but the car doesn't accelerate. The check engine light was on and the code reader said o2 sensor.
We changed the upstream o2 sensor. The
light went off but the problem didn't stop.
Please help. Btw...the car has 211, 300
miles.
