where can i find a cheap o2 sensor???

[lauj2gdsm]

Do any one know a good and cheap place on the web to get a front obd 2 oxygen sensor ???
I'm throwing check engine lights + sputtering on cold starts, so i believe its time to replace my sensor.

Yep.. Good link... ~$58 minimum.....

Also the 4 wire universal NTK brand is an option to save money if you know how to solder and shrink tube.. $40 NTK part # 21027

Any 4 wire will work provided you wire it in correctly... I ran a chrysler 4 wire I got free from a part out car. It tested fine... heater resistance and 02 volts 100% normal...I ran it for a while until I got a LC-1 WB o2 I had a AEM WB02 before that I sold...

I would consider getting a wideband if you can swing it..

Like the innovative products LC-1.. $199.00

You can tune WOT using a simple fluke meter wired to the 0-5v output and feed the ECU the 0-1v....

Its one of those while I'm in there I might as well upgrade things....

You can also just put a volt meter across the o2 sensor leads..

Not the two black ones... they are the heater...

put the ground meter lead on the blue wire and the positive on the white wire.

Probe thru the rear of the connector and obiously leave it pluged in.. run it and look for a normal voltage 02 voltage..

Also with the engine off unplug it and check the resistance across the black wires... the heater.

i have ecu+ and can view my front and rear o2s. but how can i tell if one of them is messing up? what should the normal readings be when it is cold or already hot and warmed up?
