Hey 'Dad's Truck', I use AZ all the time and there are three guys I talk to when I need real info. Talking with all the other guys is like talking to tree stumps. It is like that everywhere you go though, there are folks who are good at what they do and there are also bad. Some folks really prefer NAPA but most of the NAPA guys here are a bit snobbish. They think they're above everyone else, as though knowing anything about parts makes you special. The guys I like to deal with are the guys that either know what they're doing; don't know what they're doing but are honest about it and try their best, and the guys that are friendly. Sounds like you're one of the guys that knows what he's doing. And remember, friendly goes a long ways.

And I'll second the criticism of our database on some vehicles. It takes a little 'creative research' to find some things that you just KNOW are there, but can't find readily.
Qman, I'm always friendly with my customers. I have people who won't deal with anyone else but me (which can sometimes be a problem on really busy days) but it's nice to know that those folks think highly of me.

Well, I attempted to change out my o2 sensors last night. I sprayed them with PB Blaster (highly recommended for these purposes) and let it sit for 15mins. I could not for the life of me safely budge those puppies!! I could feel the freaking wrench bending (Craftsman brand). A closed end head wrench doesn't fit over the o2 sensor's harness, so I was using a regular wrench. I was told to use my propane torch, but didn't attempt it.
If I did re-attempt it on the weekend, do I heat the socket in the pipe, or the bottom of the o2 sensor itself?

I've also heard of people starting their vehicle and letting the exhaust pipe get good and hot and remove their O2's.
By the way, does the 302 setup have 3 or 4 O2 sensors. O'reilly's told me I have four of them but I can only find three. ???
