My van ran fine but the check engine light was on. The code read that i needed an oxygen sensor. I replaced the oxygen sensor, the check engine light went out, van drove fine for a short while but then it started to lose power and almost felt like the transmission was bad. Could the new 02 sensor be faulty or is there another problem?
