2000 neon problem

Hello, I am having an issue with my 2000 neon. I believe it may be the
O2 sensor but am not real sure. The engine light comes on after about 1
minute of operation. The car seems to have a loss of power in the low
rpm's and the higher the engine rev's it get better. at about 2500 rpms
or so it seems to run ok. If it is the O2 sensors how the heck do I get
them off? Thanks for any help.

 

Have the system scanned to see what code is in it before you start throwing
parts at it.

I get a fault code of p 1684 and p 0134 off of the OBDII

 

1684 is the battery disconnect fault, p0134 is the upstream 02 sensor
staying center and will cause a drivability problem. you don't need to
replace both of them, the one at fault is the upstream one, mounted on the
exhaust manifold.
I do it under the vehicle while on a lift, if you can see it from behind the
engine and access it, just remove it. spray it down with some penetrating
liquid before attempting to remove it.

Thanks for your help, If you be so kind to answer one more question. Do
you happen to know what size wrench it takes to remove it? Thanks again

 

I use a 7/8 box wrench to remove it, (you have to cut the connector off the
old one) and my O2 socket to install it
