o2 sensor and fuel pressure regulator

[Bigcheck1]

alright guys, i'm gonna sound kinda stupid here. i just got an o2 sensor and a fuel pressure regulator at wholesale cost so i am gonna replace them both tomorrow because i am pretty sure that they are causing me to get crap gas mileage (13 mpg is the best i've seen in months) and making the check engine light come on after i have been driving for a while. any idea as to how to get to them in order to take them out. any help would be appreciated. also where has everybody gotten the warrior shackles? i just ordered coil apcers from bluedogbandit and am gonna do those and the shackles over my christmas break when i am home. thanks guys.

If you follow the directions you won't have any problems, as long as you have the right FPR. There are 2 different ones for the 91 not sure about 92's. I just went through the same thing you are doing about 2 weeks ago. Mine went from 23mpg to 13 just like yours. Look back through "under the hood" and you'll find many replies on this subject.

Good luck on getting the 02 sensor unplugged. One suggestion was to cut the wires and splice. I cleaned mine and put it back in and it works fine for now. Take your time and you might have fun while doing it.
