So i have with me a 4cyl Mazda Tribute, and lately it's gotten horrible, a night mare. Firstly car was moving horribly lazy When i stomped down on the X rpm stick use to ramp up crazily but car wouldnt react, i've been told it's the transmission but then i got it scanned and it showed that it was the oxygen sensor and Cam shaft position sensor, the van still moves horribly lazy, cuts off at stop lights and doesnt wanna go past 2nd Gear, Help!

 

What were the codes? Did you fix the O2 and cam sensor problems? Sounds like you have multiple problems, one of which sounds like a trans issue.
