2001 DODGE NEON ACCELERATION ISSUES

What is your coolant and oil levels?

I GOT A OIL CHANGE ABOUT A MONTH AGO ALL MY FLUIDS SHOULD BE FINE.

If you want to assume they are fine and don't want to check I'm okay with that. When you troubleshoot you somtimes need to do some clue gathering. Since you don't want to, not much I can do.
Good Luck.

i checked all my levels and they are where they need to be.

When you are trying to accelerate, are the engine rpms going up and you are not gaining speed. Or the rpms are just not going up?

they are moving up but i seems like its not in sync when i press on the gas. like the timing is off

This is important so I understand you.

Have you ever felt a transmission slip?
The rpms or engine idle goes up but you don't move faster.

If you press on the accelerator and it is a rough feeling and you may or may not go faster.

That weird gurgling noise, is it like shaking marbles in a can noise?

the noise is like a grinding noise when i accerate around 30-35mph then it stops, then at 50-55 its fights to go above that, it will make a hard rev sound if itry to push on gas around 50-55 mph, then if i let off the gas a little then try again it moves a little closer to 60mph but not much

does it make a difference if it is cold (setting 8hrs) or after driving for 20 minutes or more? has the pcm software ever been updated? is there a label under the hood like this?

i have to check. i will let u know..thanx

At this point, that is where I would start, is update the software.

took it to speedy transmissions to get a free inspection. an 1hr and half later they call and tell me, that 2nd gear is gone, it jumps from 1st to 3rd. its going to cost me in between $1200-1400 to get it rebuilt......great!!!!!!. thank u so much for all your help.
