If the engine runs good on DC then You should reset the Motor settings for the decoder “the start mid and top end volts ,,, The starting voltage differs between each engine,,,, if speed step 1 it starts at a good slow smooth speed leave the start where it is,,, If you need to go to 2 3 4 etc to get it rolling,, raise the start setting,, if it starts faster than you want then lower it,,, the mid should be good at 150 the top end at 250. always think about any one that wants to run the engines at top speed and take the chance of derailing the train,,,, you might want to lower the top speed to a safe setting then set the mid to about half of that.

There are some that look very good, but have very limited pulling power, even though new. If you believe the problem is the motor, a company called Micro-Mark has replacement motors and super magnets which can make a great difference in performance. The website is micromark.com

When I go back to DCC, it is sluggish and it hesitates while moving so now I’m thinking it in the electronics of the decoder board.
Thanks for your help.

I took this loco apart and cleaned out gobs of grease in the gearboxes. This is a Bachmann that was DCC from the factory.

Engines that highball on DC poke on DCC. Don’t know why?I think it’s the DCC making your engines weak. Have you tried them on DC? Are they faster & stronger?

But there’s also a factor noted in other posts: some of those older motors draw more current than those commonly used with DCC. If they draw more current than DCC can provide, they will not have the power equal to motors designed for use with DCC. They’re still good motors, and they might work well enough for a time, but they could also over stress the DCC system causing a premature failure.
