vs clubby issue

[mr_clubby96]

hey guys just wondering how can u tell if a 02 sensor is ***t

also on the vs 5.0l is it 2 wire or 4 wire on the 02 sensor

thanks

[Damo304]

it will run a bit rough and will more than likely make the engine run rich on fuel, not sure how many wires the 5l are

[Sgt Santa Cruz]

vr-vs series2 are 2 wire s3 vs -vt are 4 wire also vr-vt 355 factory motors are 4 wire

you will be using excess fuel too

[mr_clubby96]

cheers guys will it make any loss in preformance or in drivability wise

[VrWagz1]

i would think so, but how noticable it is i dont know.

[chrisdoesitbetter]

you will use noticably more fuel, idle will be rougher and it should set a trouble code so check your diagnostic...

its got a aftermarket ecu i noticed today when i drove the car home from work my 02 sensor was slightly white??

[mr_clubby96]

what does this mean?

[centy]

it means check for error codes.

[mr_clubby96]

could this be caused by aftermarket ecu

cause my car hasnt been tuned so its running rough could this be the cause of it to get confused ...

motor is fresh and also running a diffrent throttle setup then it was before we triggered to run real rough
