Small Update:
Pulled the car back in the garage to set the ride height, searches say i should sit around 27"-28" on a 26" tire, took a measurement before i threw the car on jack stand, 24" fender to floor ! lmao No one the hell stance.
Also, finally got the gauges working... but i think i MAY have a faulty sensor. The car starts it reads 14.7. Which i thought was odd to start anyway bc it isnt tuned. I didnt think there would be a chance it would be stoich first try. So after a running for a few seconds, the wideband starts to count down.. 14.7-14.6-14.5..etc etc. The car then lets out a pop(which its been doing, im just assuming bc dat untuned idle) but once the car backfires, the widebang sweeps all the way to lean and then reads "---"
I was able to replicate this a few times, so i can try to grab a vid.

If you have a bad tune, the sensor will say F you if you keep bouncing it off the spectrum of rich/lean.
Just be sure you have the heater circuit powered up every time you run the car.

The wideband 02 sensor has a 12v feed to it to heat it, so that it doesn't die when you run the motor.

If you just do key on (don't start), the sensor normally will start at 14.7 and then creep up to max lean as it heats up. Check the manual for it's calibration process when it is started to see if it does the same.

So tired what BLS said..
Key on, not running, gauges does its little cycle. Starts at 14.7 and stays for a minuted, then begins to drop and then the lean hammer comes and it full sweeps to lean and reads "---"
Car does the EXACT same thing when its running.

Watch the datastream on the car's actual o2's. See if they have similar behavior or if they switch from very low voltage to almost a full volt or something else.

That has to be done threw HP tuners correct?
Ive read into the AEM wideband more and it seems a lot of people are knocking them. I purchased this one second hand, albeit from a buddy, so who knows. I dont think my friend would sell me a bad gauge knowingly. I also read that they are very tempermental with how they are wired. So ill be looking over that next.

That 27"-28" was measured to the floor as well ?
Ride height should be measured from the bottom of the wheel edge to the highest point of the fender

The thread i saw on tech was measuring from hieght point on wheel arch to ground @ 27-28. I have my car at 27" now and it looks about were it should be. Ill grab some pics today.

Could be a bad sensor Beggz.
Have you tried the manual calibration for the wideband?

Let the car idle for about 2 mins last night and nothing on the wideband. Just cycles threw the number, starts 14.7 and then lean hammer after a few seconds. Reads "---" the entire time the car was running.
Im gunna check over all connections a today and go from there. BLS said possibly just wire the power direct to batter just to test so ill prob do that. If that doesnt solve it i will brakeclean test the sensor.

Once you verify the connections, take the sensor out of the exhaust and do a manual recal of it.

How does one accompish? Just run the sensor to atmosphere instead of in the pipe?

Never mind, apparently AEM is just calibrated from factory and never able to be adjusted.

That's what I did with about 1 inch of rake added into the rear.

So i finally had some time to myself yesterday to get back to work on the car.
For starters, i tore all the gauges and wiring out. Just from moving the car in and out of my garage a few times i grew annoyed with the pillar pod set up. So ordered some more ABS plastic and fresh hole saw blade to do a pod in the vent.
ANYWAYS...
As previously mentioned, one thing that could be causing the issue im having is a **** ground or power connection to the the gauge. For testing, i ran the power wire directly to the post were the battery cable powers the fuse box. Then ran the ground for the gauge directly to the ground block i have under the hood. Which i know is a good ground bc everything else thats hooked to it works.
With the key on, gauge did the same exhaust thing. Started the car, same thing.
With the next step being to test the sensor i put the car up on jackstands so i could slide my belly under. It began to rain while i was doing that, so i just cleaned up once it was up. But while placing the jack stand, i saw 1 of the slip joins on the exhaust was open. About 8" after the wideband.

Slid myself(and belly) under car and removed sensor from pipe.
Soaked rag with brake cleaner and it read 14.7 once power, and slowly swept to full rich. So the sensor should be good, no ?

Seems that way. Double check no other leaks upstream and plan a date with that tuner.

Could the down stream leak cause it?

Seems pretty unlikely. If it was closer, maybe but not that far downstream

Looks like the only differences between the o2 plugs is 1 has solid purple wire, 1 has purple with white stripe wire.
Who knows which goes were
