Before I go and buy a fuel pressure regulator will it work to tone down the fuel intake , so I am not running so rich? I installed my a/f gauge today and it is all the way on the farthest bracket in the rich zone.

So will it work?

I have intake, just some plugs, and a full exhaust. I replaced the 2nd O2 sensor 2 times, and it keeps throwing a code somthing about heat of the sensor. I looked it up and it's a common code to throw when you have a test pipe on. So now I think I am in limp mode and it's throwing all sorts of fuel at it.
