how do you know when it goes bad ? symptoms ? sorry guys its a newbie question but i still haven't got my helms manual (backorder)

Also where can i get a wideband o2 ? recommendations ? alot of tuner shops i go to don't sell any

TIA

 

btw i did a search, no luck.

 

if O2 is bad usually car will run like **** as it not get the right information to the ECU to add or take out fuel..

Also code 43 ( I think) too rich or lean also will flash.

Anyone kno a which O2 WB sensor to get ? does anyone here use Halmeter ? impressions ?

 

I would get the AEM WBO2, best value for your money... $360 shipped @ KS Motorsports. You can put it in 0-1V range in order to use your stock ECU, or you can switch it to 0-5V range for an EMS or whatever.
