The car was running perfectly well, but I took out the high beam fuse and tarted it up to go to the autoshop to get a new fuse, but as soon I started the car up check engine light came up and the car went into limp mode. I noticed I had taken out a relay in order to take out the fuse which I ended up putting back in the wrong direction, so it popped up 20 codes, but when I got that sorted it popped up 8 codes, I tried to rese the ecu by disconnecting the battery, It was fine after that but the issue came back, now I dont have a check engine light but the car is in limp mode the car has a JLT cold air intake and 410 gears the car was tuned for 93 octane but is running the stock tune now. How do I fix this and what is causing the issue? I have a hunch that it is something related to the fuse box but cannot figure out what

 

why is the car running on the stock tune? pretty sure that JLT intake requires a tune, and it won't run right without the tune

I am not sure if that is the whole problem, but I would at least eliminate that before troubleshooting the rest, since it will be very hard to determine whether the tune mismatch is causing the problems or something else

 

P0010, P0020, P0102, P0135, P0155, P0443, P0446, P2008P0010, P0020, P0102, P0135, P0155, P0443, P0446, P2008 P0010, P0020, P0102, P0135, P0155, P0443, P0446, P2008P0010, P0020, P0102, P0135, P0155, P0443, P0446, P2008

 

the car was running a 93 tune with the intake and 410 gears but since the engine light came up I switched it to factory tune to see if the tune was causing the issue, I can change it back to the 93 tune with the intake and the gears but the codes that I have are P0010, P0020, P0102, P0135, P0155, P0443, P0446, P2008 none of them related to the air intake or the gears.
