Car turning off

[Javeed Mohammad]

Well today I installed new o2 sensors and I know the installation went perfect but for some reason now when I stop sometimes my car just turns off. What do you think it is the filters injectors etc need help on this one

Did you disconnect the battery while doing the work? If so, it's normal for the car to run like crap after a battery disconnect. The PCM needs time to re-learn new idle trim values.

If you didn't disconnect the battery, then check for blown fuses. Especially F2.2 and F2.8 in the CJB. Today's cars have a ton of "always on" circuits and it easy to blow fuses if working on electrical hot.

i cleaned the idle control thing, the one next to the throttle body and i dprove it for like ten min and it ran really good. i cleaned it with some carb cleaner but i dont think this will work for long the idle when im coming to a stop is insanely low so im hoping i can find out what it is.

Check for vacuum leaks. Perform the IAC basic functional test.

Note, it not recommended to clean the IAC with the black vent.

If you still think this is an injector problem, consider an injector cleaning/flow test service such as Injectorrx.com. Once cleaned they are as good as new. Cheaper than new.

Low idle can also be caused by poor cylinder to cylinder power balance (1 or more cylinders not pulling their weight).
