Truck surging

Hello,

My truck all of a sudden started surging at steady throttle. It doesn't do it when accelerating, just when you are up to speed and cruising. I got these codes 0500,0753,0713,0460,1763,1693,0177,0602. I think maybe the tranny is toast. what do you think it could be.

Thats alot of codes. Fix the codes and the surging will probably go away. I would guess that all of those codes are related and one fix will fix all or most of them.

I honestly dont know where to start.
0177 water in fuel
1693 companion code
0460 no fuel chang over time
0602 fuel calibration error
Those I think I can do. The others I don't know. I know what they mean.
I am no expert mechanic.

0500- Speed senson, basically like spinning your tires.

My truck is getting 0500, 1693, 1694. I dont know if i would call it surging, but it feels like my foot falls off the pedal when driving. Still researching.

Both! It does feel like foot slips off peddle. I am wondering in the vss can cause the other codes. I had the rear vss replaced about a 2 month ago. Engine sounds fine>

A good start is to check all the grounds.

Might be the injectors that you have installed, i have heard that alot of had similar issue and it all seems to be after they put injectors in.

I doubt its the injectors. They have been in for 1.5 years. Will check though.
It feels like it is defueling and then fueling again. What grounds should I check and where are they?The 0713,0753,1763,0500 I think have got to be related some how. Seems to only do it after the truck comes up to temp.
Any input please
Thanks

Well i cleaned the batteries. Lots of corrosion. I also wrapped the black wire in foil. I hope this help, but I am not holding my breath. I am resetting the apps right now.
I'll keep posted

Isn't there a speed sensor on the tranny, as well as the diff. Where is the one on the tranny located?
Thanks
