Forget The O2 Sensor!!!!!!!!!!

WAY BAD CALL 94JIMMY!!!
A finely tuned motor does NOT even use the O2 sensor. A finely tuned motor uses all of the O2 which gets burned in the combustion process, and the O2 sensor does no work. A poorly tuned motor lets O2 get through the combustion process (by not burning it all), and into the exhaust, and the O2 sensor tells the ECM that compensation is necessary to fix another problem. If you'd like to see that in print, I'll be happy to get it to you. A bad O2 sensor is an extremely common myth!!!

Uhhhhhhh????????

I'm not sure why you posted this thread, but...
Just because a "finely tuned" motor uses all of the O2 that comes into the chamber does not mean that the sensor is not working. It is absolutely working. A sensor is just that, it does nothing but sense. It recives a signal and sends a signal. I'm sure you realize that a motor does not stay in tune by itself. It needs constant attention whether you know it or not. Those sensors help keep the motor running efficently until scheduled maintence time. Sensors can and do go bad including the O2 sensor.....If the engine didn't need it, they wouldn't use it.

i would love to see this in print

Unplug a few of your injectors, and remove a couple of your plug wires while you're doing away with your o2 sensor. Those plug wires are just extra weight.

:lol:

This is hillarious. Remove them and see if the 'check engine' light doesn't come on....it will. :grinno:

Yes, the ECM uses data received from the 02 sensor(s) to correctly adjust the air fuel mixture for the ever changing conditions. This is a constant process when the system is in closed loop. Without the sensor operating all of the time, the engine performance would certainly suffer with a moder fuel injection system.

And yes, the sensors can and do go bad. Either electronically, or other means like fouling that puts them out of specs.

And where did this thread come from?

Probably an online "troll"

The only way to get rid of the o2 sensors is to fool the system by putting in o2 sims. And all they do is simulate the actual sensors as if they were working properly. Kinda stupid if you want to make sure your motor is still running correctly though!

come on guys, havent we beaten this guy up enuf already? no. ahahaha. please dont listent to this person if ur lookin for "tuning" advice. maybe u could get rid of the sensors on the very first cars ever equipped with them, but not new ones. im curious tho, because i like to give people the benefit of the doubt: cbec1999, do u have them on ur truck? if not, and it still runs properly, let alone at 100% percent efficiency which is all but impossible, then we all owe u an appology.but i doubt it. ok now i think hes been properly abused emotionally. and the simulators arent all bad if u have an engine tuned to a point where u need them.which i dont, so i can only offer a partial opinion.in fact, scratch that. i cant offer one at all lol. i just got a big mouth. id leave the sensors on unless i had no alternative. its just not worth the headaches. thats an opinion that comes from experience.i have an old truck thats not at all legal and never will be, but as far as the new one goes, its gonna stay on the up and up untill it costs me a race with somethin from Jay-pan.(no rice here baby!)

I'm telling you, the weight loss from yanking a few of those plug wires is hard to beat.

heck yes cuz! im from jersey where races involve not just the top speed, but how quick u get to it.every hundred pounds is a 10th in the quarter mile they say...

sorry i almost forgot lol. look on here for Slowprocess, hes runnin a not-so-stock 6.0 in his 1500 and went 12.5 at 105.ask him if hes got sensors on his exhaust.i couldnt tell u if he does or not, but whichever the case is he appears to have made the right move to me.

I'm pretty sure he doesn't..seein as he has long tube headers and cutouts..

This person is full of what Penn and Teller say,B.S.The O2 sensor can go bad bad many ways, even antifreeze after replacing the headgasket or headgaskets on certain vehicles.Electronic Fuel Injection will not work right without the O2 sensor.

Yup, if you still want to see it in print, I found the article. How to tune a TPI, Corvette Fever, Nov. 2000.

How to upload it there, mods?

Maybe I should tell my tuner to delete the front two o2 sensors
(weight reduction,lol)since the back 2 are already deleted cuz of headers,lol

Welcome to year 2005. :runaround:
