Hey guys. I have a 2001 tacoma. I got a CEL a couple days ago. toyota shop told me it was the front o2 sensor. I went and bought a censor from schucks and installed it. The CEL has gone off but....
Now when accelerate I get a "chug" almost like I've pushing the gas petal up and down real fast.
It is a Bosch o2 sensor.

Any ideas?

Thanks!
