No check engine light but truck won't accelerate

What is your question?

I had the po720 code come on I found an exposed wire I put liquid tape over to cover it up but the check engine lights not on anymore and it's still not going when I put the gas pedal down if I barely give it gas it seems accelerate smoother

What makes this problem better or worse?

It doesn't matter if the trucks in it cold or warm

How long has your 1999 Dodge Ram 1500 had this problem?
