Update, I drained the gas tank and visually inspected it and no water or debri was found. Also I got the supercharger back in when it was serviced/repaired for the oil leak. It still drives the same. I randomly had my traction control and abs lights go off and is now dissabled, not sure if it is...
Yea i'll try the bad gas thing, I did run the tank empty once and had to fill with the gas cans but it wont hurt to try again.
@Ruiner46 When I took it to the tuner he said 800 bucks to take a look at it because he couldn't work with lund's tune and needs me to get an stc tuner. He also said...
Very helpful, I'll give it a shot. How did your car idle, did it go up and down consistently like here or more of a stall at a red light.
Also the engine tick was just my injectors operating normally. I definitely had an exhaust leak near my o2 but I fixed that and it helped a lot, the whole...
Update:
Changed the fuel injectors to stock injectors and also the tune since it would not run on the aftermarket injectors. No change in rpm fluctuation but definitely noticeable improvement in getting rid of the hesitation. However, the rpms would really do some weird things like hang at 1200...
Phew! Was really stressing the compression numbers since I did it.
I did both the KAM relearn and crank relearn. No result.
On my list of parts to throw at this is:
Fuel injectors /cleaning
Crank position sensor
Camshaft position sensor
Cam phaser
I'll be all out of things to try after...
Lol the dreaded test I didnt want to do was done. These are the results:
195, 210, 210, 210, 195 190, 200, 180.
Cylinder 8 was the last one with 180psi and that might be the culprit. But I did a leak down test right after and it sounded the exact same as when I did it from a good cylinder...
I ended up isolating the oil leak to be from the supercharger. The supercharger is off of the car now and is going to be sent back to be repaired. In the meantime, I have the serpentine belt bypassing the supercharger, and the car is basically stock now. HOWEVER, I still have the same idle...
This is the oil from the supercharger on the dipstick and the other one photo. The maf sensor tune was dry and I'm suspecting because the oil had to come from the outlet of the supercharger all through the other pipes and intercooler.
Just changed the throttle body and the ignition coils (did a KAM reset as well afterwards) and no improvement. HOWEVER, I did find a ton of oil in the intake and behind the throttle body, and a lot on the outlet of the supercharger. I literally just changed the oil 350 miles ago for both the...
Yup your right. The car had the supercharger installed by previous owner and he said after 6 months it started to have the idle issue.
It was way worse before and I had a cylinder 8 missfire/missfire detected on first 1000 revolutions and but those were both fixed when I changed the bad 02...

I have a 2016 mustang GT with a Vortech v3 supercharger on it tuned by lund.
I have left and right upstream O2 sensors, but no cats, and O2 sensors. The only codes I have are for the missing downstream O2 sensors.
I have 3 inch long tube headers with an X pipe that goes to a 2 1/2 inch...
