    02 sensors

    my car is acting funny i put lt headers in and i do have the bosch sensers. it feels fast then slow this happens every time i drive it. my light is on but thats the rear 02s. thats the only codes. can u check the 02s with the key in the on position? if i punch the code in my diablo tuner it will say slow switching. i had more codes for 02s but again this did not show up i punched it on the tuner

    After a lt instail, if you used cermaic headers you may have fouled out your front two plugs due to the ceramic flaking. It will cause a "lazy" sensor or slow switching.
    Take the sensors you had in the rear and try them upfront and see what happens.
    Also post up your codes so we can drop you more info.

    You have a tune installed w/Diablo? Or stock tune?

    its the stock tune. i scanned my o2s on the diablo when driving around and they were lazy and hanging. also i had a exhaust leak after the o2 where the collector meets the y pipe can that cause a problem?? i still am trying to find out if my o2s were black why are my plugs white as hell.??

    It's normal for them to be black, even if plugs are burning ok. You probably need a tune. A few other posts had same issues and a tune was suggested. Have you tried the Diablo tune? Any difference?

    Generally speaking 02's are maintainance items and should be replaced on a regular basis.

    Most tuners say every 40,000 but I tend to stretch that a little bit.

    But what you will find is,,,if you have sensors that are borderline and then install long tubes,,,,you will get those slow switching codes,,,,due to lazy 02 sensors being further down stream.
    Only way to fix that is to install a pair of new ones. Unfortunately these new cars aren't cheap to maintain.
