my jeep was acting like it was out of gas between the speeds 0-30km...at times on idle it was nearly die...when it bounces when it feels like its going to die i feel and hear a knocking sound when i'm trying to excellerate through it

The problem is I took it in and they scanned the computer and said it was the O2 sensor...fixed the problem and i was off. One the way home the engine light comes back on and it starts all over again...Saturday i take it back and they claim it was a faulty part order new ones and i wait..they fix it and i'm off for some riding in Chillwack...not for long it starts again on the way home!

are these mechanics missing something here?

Something upstream is killing the sensor.....they don't simply die.....like catalytic converters, they are murdered......take it to a better shop for some diagnostic work.....could be one hell of an overfuelling injector, a loopy MAF sensor...loopy MAP sensor....could be anything.
