Which fuse box? Can you elaborate which one it was?

The fuse box under the hood on the left side of the engine bay where the ecm is.

Thank you mustang281man!

Should have been the first thing I should have checked.. Unfortunately, mine was not blown. I still pulled the fuse then unplugged ecu and plugged back in along with a few other things.

Update: E55 is back in action! Thanks to SIR BOOST A LOT and the help of Shardul, Mustangman281, VegasTrashed and other valued members. I was able to solve the issue. I did have a feeling it was simple and nothing major.

I'm unsure what exactly it was because, I did a few things at once. I did not want to keep starting the car and have it stumble and foul the plugs or mess with other things. So it was a 1 shot deal.

Maybe it was a hard reset, ESP fuse reset, throttle body, or all of the above. But, the car sounds good and back to normal. Did the Throttle body reset and will do sneaky ecu reset and go for a drive! I guess it will be a merry christmas after all!

Thanks to all valuable members who helped me! Cheers, Merry Christmas, Happy Holidays, Happy Hanukah!
