    Well Virgil was a good enough dude to hook his laptop up to my truck (he has HP Tuners) and we drove around for awhile to see if there were any problems. Turns out, the O2 sensors are barely registering and HP Tuners is giving an error message. This is all dumbspeak - I'm not sure of the exact terms, but anyway, something is wrong. Virg is gonna email me the file and I'll send it to Allen and hopefully he (or anyone else) can give me some advice.

    yessir...I mean they weren't even registering. Sometimes BARELY. Other times they would spike a little and then go back down to virtually nothing.

    I'm needing some input guys - I don't have a clue what the problem might be. Maybe I should have Allen send me a tune with them deleted? Is that an option?

    There's sooooooo much I don't know. Thanks man. Still need to figure out what's up with them. Hopefully it's nothing too serious.

    The sensors are supposed to vary up and down constantly. If they have low voltage readings all the time something is wrong.

    See, I don't know all the lingo. Yes, that's exactly what they were doing - little to no voltage.

    What could some of the causes/issues be?
