Is I press on the accelerator the car begins to tug as I'm driving 40 to 60 miles per hour tugging may increase when I take my foot off the accelerator it doesn't tug. I've tried several gas treatments and the treatments and clean out the jets. I don't know what's causing the problem or how to fix it.

Good morning,

There are no additives that will help injectors. If it is an injector, a service needs to be done that will clean them. It requires special equipment to disable the fuel pump and injector a special cleaner directly into the injector for cleaning.

How old are the spark plugs? This is the most common failure for this.

Also, how long has it been since you changed the transmission fluid and filter?

I changed the spark plugs about 1 month ago and I had to change the transmission fluid three months ago, but I did not change the filter.

Okay, I doubt the filter is causing this issue.

I would suggest having the injectors cleaned.

Yes, it runs good besides the hesitation. hesitation starts at around 2 RPM's.

I understand. It could still be an injector that is not spraying the correct pattern.

Not without special equipment to inject a cleaner directly into the fuel system.
