What does if it mean if the check engine light comes, after having a new oxygen sensor fitted?

The car started to pull, almost like it wasnt getting enough petrol through. The check engine light came on on long journeys so i got the oxygen sensor changed as thats what they said was wrong. The pulling then stopped, but only about a month later it has started again, so its jerky to drive! If you knock it out of gear and rev the engine a few times its seems to sort the problem but only for a short time. Its worse when you start the engine from cold, but still does it, but to a lesser point when warm! any ideas?

I would check the engine codes again. it doesnt sound like an o2 sensor because the computer does not use it when the engine is cold. sounds like you may have a fuel problem or an ignition problem. check the fuel pressure and pull the plugs and see what they look like

Have it checked by a qualified tech. They should understand the system and controls in place to control the emissions
Most cars have more then one oxygen sensor, so it's possible that one of the others have failed. It also sounds like you have something else going on, best bet would be to take it to someone knowelgable, have them test for fault, clear codes, retest then run the tests on the first code that re-appears, it might not be the 02 sensor that is faulty but something else causing a false code.
Check and or change you fuel filter if its dragin under lode then you have a feul prbl. also try disconecting the posative poast of your battery for two-three mins. it will erase any problum codes and will give a new code if there is a problum with something els . if your car is a dodge product you can retrive your one codes turn the key on and off three times then on and count the check eng. lite flashes blink blink. . blink blink blink is code 23 for example good luck BRAD
