Bad oxygen sensors?

Alright, I thought it might but wasn't sure if it would have that much of an effect. Thanks for the help!

The O2 sensor keeps failing and I've replaced it 4 times in the last 3 months. What else can cause the Os sensor to fail. Need your help
Thanks

Can an o2 sensor bung be replaced w/o welding?

Alright my head gasket went out so I replaced that and while the exhaust manifolds were off I decided to put headers on I cant route the exhaust back to put an o2 sensor between them so I put it in one my truck runs but not nicely. Is there any way to hook an o2 sensor into each pipe and splice the wires to feed into one plug in? Or is there another option besides an o2 sensor elminator? Idont have very much money so I cant give a donation. Alright I tried re torqueing the head bolts and managed to snap one can and will my engine run with one bolt missing the threads are 3/4 the way in and no coolant came poring out

I have a 1991 Ford F150. It started dying on me when I would stop at lights or for turns. After a couple of weeks of this the engine light came on and I had it tested and was told the O2 senor was making engine light come on. Would the O2 senor cause the problem I was having?

I was told the code was 41 and it is a 5.0 engine.

Thank you so much for the information.

I replaced the O2 sensor, fuel pressure regulator, and the MAP sensor but it is still dying on me when I come to a stop or at a very low rate of speed. Please help.

My fuel pump runs, my ignition is sparking, but it seems as though the injectors aren't working once I crank the engine. I can hear them click, when I first turn my toggle switch on, and when I first crank it it hits like it wants to start, but won't unless I turn the switch off and back on, and it just hits again but won't start. New fuel filter, distributor, coil, stator, plug wires, and fuel pump, also O2 sensor. Ignition system completely redone, and mostly all new fuel system, except injectors, and computer.

My fuel common rail psi is 45-50

My engine is a 4.9L inline 6 also known as a 300-6
