I'm in the process of replacing the not-so-costly parts that are replacable and will improve overall quality.
And now, I've come across the difficulty of a beginner trying to replace the O2 sensor.. I can't find it. I'm fairly new to all this stuff, but I want to learn and be able to do all this stuff myself. I did a search a came up with one picture of the sensor's placement, but it doesn't match on my car. Are there other setups? And does anyone have a pic of how it would look in a 91 Firebird 3.1L? I even bought the Haynes manual but the illustration isn't clear. Thanks

 

on my car its on part of the exhaust just just behind my passenger side front tire, look around there and you might find it.

 

I've spent hours upon hours searching where other posts have said to look and also according to the Haynes manual, with no luck. But after reading your reply, I found it in 1 minute. THANKS!! I love TGO

 

no prob, figure id share what little knowledge i have on the subject of cars
