Can you re-calibrate your particular wideband?
Has the engine thrown any codes?

Took out the injectors and brought them to a shop for testing.
Although the AFR Gauge says that the engine is running lean the exhaust smells like fuel. This gives me mixed feelings about really running lean.
So would it be possible that an injector isn't working good (stays open) and that the engine gets to much fuel instead of to few?
The Lambdasensor is only installed on 1 side of the exhaust so it can only read one side of the engine.

If you have no spark on one or more cylinders you will get a lean condition. WHY? Because there is no combustion to burn mixture so the O2 will remain. As well this would explain teh rich smell of the exhaust because again the fuel has not ignited within the A/F mixture. As the unburned mixture passes the O2 the O2 (which detects O2 presence) senses the o2 and this the lean condition will be present. I suggest getting out your laptop, uploading SCT datalogging software (assuming you have an SCT tuner) and set up to datalog misfire on all eight cylinders. Also observe Lambse bank 1,2 and AFR bank1,2. Determine which bank is lean and then target those cylinders for misfires.
This would be a beginning from an electrical aspect..............
One last thought from a mechanical aspect. Are you hearing any odd knocking or loud tapping? With the odd running AND teh hot condition you are noting you may have a failed Cam Phaser. I went through this with my 2005 GT. No CEL's just a rough running, no power, and a knock from up high.

Since you said the engine is running hotter and sounding different, is there a way to check your o2 sensors? Maybe a clogged cat converter if you still have them installed?
What is the short and long term fuel trims showing? Are they in alignment with the AFR gauge? Could be your wideband has gone bad?
I know this might be a stupid question, but do you usually clean your engine bay?
Do you still have your charge motion control valve operational?
They do seize up due to carbon build up and cause all kind of issues!
This is good info. So are you saying a misfire can result in an unburnt fuel smell along with a lean AFR reading? Do you know offhand what PID logs misfires? Is it the misfire count?If you have no spark on one or more cylinders you will get a lean condition. WHY? Because there is no combustion to burn mixture so the O2 will remain.

The charge motion plates are "throttle valves" that sit in the intake manifold runners to speed up air intake velocity during slow engine speeds/part throttle driving. It's also there to help fuel atomization during part throttle to maximize gas mileage and street driveability. At wide open throttle the valves open up to allow unobstructed airflow. I would rule out any ignition misfire issues before looking at the motion plates.What is that? Never heard of it before!

I always forget about these things on the 3V. They did away with them on the Coyote, and my 05 didn't have them after the Saleen twin screw was added.
They were added back to 15+ coyotes fyi. On the 3v they were driven by an electric motor on the new coyotes they have two pneumatic control actuators on the back off the manifold, they look just like wastegate actuators and use a solenoid to change airflow to the actuator to open and close the runner valves.
