Hey guys, and gals....I have a 96 9C1 4.3, and it stutters at times, I wonder if it is bad gas...I have been noticing it more and more..little but of stumble. Can someone tell me if there are 4 o2 sensors in the 4.3,(and where might they be located, and which brand would be a good replacement?) I know there are 4 o2's in the 5.7 LT1 1996 models.
Thanks all...

The best place to get them is from Sam. I think I paid $26 a piece.
