wideband info
I have been faking the funk for while on this subject what the purpose of a wideband every thread. every meet i goto i here wideband 02 what is it, what does it do and when do you know its time to get one
First, SEARCH next time
the wideband lets you know the ratio of air to fuel in your exhaust stream, this tells you how lean or rich your car is running.
you need a "wide" band because it has the resolution to tell you mixtures ranging from ~9:1 to ~22:1
your car comes stock with a "narrow" band which only tells if you are either rich or lean with respect to an afr of 14.7:1 afr.
why 14.7:1 afr you ask? this is the stochiometric afr that give you complete combustion of fuel (theoretically), and therefore the cleanest emissions

Come on now...we all started somewhere. 
A wideband O2 sensor is an Oxygen sensor you put your exhaust. It measures what the air to fuel ratio is the engine is running at.
If you don't have enough fuel, you get detonation or pre-ignition where the fuel in the combustion chamber auto-ignites without the spark plug firing. This sends little "shock waves" through the combustion chamber that end up hitting the "shock wave" created by the spark plug, creating cylinder pressures exponentially higher than what the motor can handle. Continuing this process will eventually kill your motor.
If you have to much fuel, the car will usually misfire or sputter because the additional fuel is putting out the spark created by the spark plug. It also makes carbon build up on the piston top and cylinder head which can lead to hot spots, which cause detonation/pre-ignition.
There is a lot more to it than that, but that should get you started.

ok maybe i should put it that way...
my innovate is not working for some wierd reason...so i hooked up the motec lambda reader...it reads anywhere between ( 0.88->0.93 )
is that safe or not ??
(i tried searching...i swear to god you dikheads)

so your running between
12.9:1 to 13.6:1
richen that bish up!
that is assuming you are using gasoline
how come i am too lean?
