Our cars only have 2 o2 sensors, they are so dumb compared to cars with 4 sensors, 2 for each bank.

The pcm does not care where you get the readings from because it cant even tell which side of the motor is having the problem to an exstent.

So putting it in the front crossover is fine and makes it easy to get at. It not something you have to do.
yeah, i knew it was something with the valve train and/or topend somewhere... I just didnt know if he was in the beggining, middle, or end of what he was doing so in my head i figured he could have been doing anything.......Oh well, but anyway thats the first ive ever seen a O2 sensor in that location on a 3800....LOL, I thought it was a special mod or something....well at least u have easy access to it
