99.5 has a miss/buck during slow acceleration

[Wicked 72]

I have a 99.5 6spd. I have noticed that during slow acceleration and some times while cruising, my truck will act like it has a miss and sometimes buck a little. under normal/hard acceleration I dont not seem to have the issue. It just started so Ill try a few different driving scenarios to see if there is one thing that effects it more. I will post more on my findings but if you guys come up with anything, I would love to hear it.

Check your UVCH conections its very common for them to get loose or burn up like mine did.

I have been playing around with it the truck all day today and it only has the miss when I am speed correcting. Like when your just going 50mph and you drop a couple mph and you just give it just a tiny bit to get it back up and has a miss that comes and goes till i level off or if I give it just a bit more on the peddle then a tiny bit. Would the UVCH cause this problem?

Also The problem does not happen when I hit large speed bumps or bumpy highways so it makes me think the UVCH isnt loose but I honestly dont know how it would react.

I got under the valve covers finally and the harness on the drivers side starting to wiggle loose. However it was barely out of position. I grabbed a couple of quarters and cuttem to fit so thats one issue fixed but not the cause of the problem. I have noticed that it starts to do it when the truck is warmed up also I have noticed that now that its gotten very cold over here, when I let it idle to warm up the RPMS dont shoot up anymore. Any ideas?

Does the engine get quieter and you hear like the sound of wind (the turbo im guessing) as the truck loses power and slows down?

All my piping is good. From everything ive messed with so far it looking like a bad injector. I am going to take it to a friends shop and put a reader on it and check the values. it runs fine and accelerates perfect.
