How countless o2 sensors does mine 91 S10 pickup v 4.3ltr have? ns guessing I have only one in mine Ypipe? am I best or wrong?
Actually if who knew, it would certainly be yes, really nice if someone might make a perform of every the years, how plenty of they had, and where they are. Then do it a sticky. Just a thought. Ns think mine 97 4.3 has 2 or 3, anyone know?

1 on each side the the Y pipe and 1 ~ the cat.. I don"t believe theres one prior to the cat or resonator, however i must look sometime.. ANyways, you need to go loook, you"ll have the ability to tell what an o2 sensor look at like..

my 97 4.3 5spd has 4 1 after each manafold, one prior to the cat, and also one ofter the cat. Ns get about 18 mpg the truck has 125,*** mile on it. Would changing the 2 in the y pipe aid my mpg?

The 3 prior to the cat impact mileage. Changing those 3 would certainly be far better IMO.my 97 has actually 4 and also 125k ~ above it together well. If you change them permit us understand the difference.

So that sounds prefer the 97+ all have 4 the them, one before and one ~ the cat, plus one in ~ the collector in each manifold. I guess it was the 97+ that had actually ODB II with 4 O2"s. 96 and also earlier were ODB I? Is that right?
Nope, OBDII was presented in 1995 with my Blazer and 4.3L. Yet it only has actually 2 O2 sensors. One before and also one ~ the CAT. The 1996+ have actually a an ext advanced version of the OBDII v 4 O2 sensors.
my 98 only had 2 prior to the cat...one in either next of the y. Walk I miss one, or walk they readjust it in 98? I think the OBD ns systems have actually one pre-cat and one post-cat O2 sensor.
