FORCE FABRICATIONS

i know everones gonna say im crazy but....if i put my truck in 4 low i lose my throttle ...what i mean is i have to push the throttle almost half way to the floor to make the truck move...ive never seen this before and when its in 4 hi its normal...its soo bad that if i leave it in 4 lo and drive it around my yard for a while it will actually trigger the "wrench" light to come on.....truck is 04 f150 with a 4.6

The low gear in the transfer case could be binding up. Maybe? That's a weird one.

Is it that the engine is really struggling or does it seem as if there is just no throttle?

When the wrench light comes on, what does the code reader say? If you haven't checked and don't have a code reader, you should go to an auto parts store and have them pull the code.
