I have all 4 o2 sensors go out wood it be better 2 just get new o2 sensors or just get the o2 deleter and do that?
Yes, the two front sensors are used for engine control--directly in closed-loop mode and indirectly in open-loop mode, as the long term fuel trims are learned from the short-term trims.I'm pretty sure you need at least two for the ECU to operate your engine correctly.
Oh. I have never heard of a scan tool (at any cost) that did not read the OBD2 codes.Mine don't tell cods it tels me what it is lol it was about 5000 for it
Don't do deletes. O2 sensors measure oxygen and adjust your air fuel ratio based on how much o2 comes out. It fluctuates from rich to lean. You can run a car without o2 sensors, many people do, but its not just that simple. IMO for a reliable DD the o2 sensors are a must.New me said:I asking wich is better new o2 or deletes
+1 they are a must. I understand what he means by knowing when o2 sensors are bad because you will notice poor performance great amount of fuel consumption idle surge etc. of course you all know your car with overtime driving it. That's how we notice all these lite things about them. With that being said you can use rear deletes or mil. But you still have to replace and use o2 sensors. Your car will cost more to run with out them then it would just to replace them. Do the math @ $3.29 a gall and with out o2's your filling up every three to four day with fuel consumption. To where if you just spend $100 and replace them it would be more cost effective that way...Dub9stang said:Don't do deletes.

Agreed so just do as we tell you "New Me" lol joking...cliffyk said:As others have said, the front sensors are essential to engine control, however the rear sensors have nothing to do with operating the engine--all they do is monitor the catalytic converters, MIL Eliminators are fine back there.
