2000 Pontiac Bonneville 6 cyl Automatic 109897 miles

I have been having trouble with my car lately it's a Pontian Boonivelle SE 4 Door V6. Here I go. HOPEFULLY this makes sense. "You know how when you step on the gas and usually you will pick up speed lately for about the past 2 weeks or less it's been ging slow. I.E. On the odom. It shows I'm going 65 but it feels like I'm going 30. I just haven't had time to have it looked at. In example again. If pushing the excelaertor it should read 65 when on the freeway but I know my car and it feels like I am going 40 not the actual speed. If I push the excelartor more I just feel like I am going to brake something.

Have your vehicle speed sensor and your throttle position sensor looked at. In that order of course

You mean like a cable? Check and see if when it was tuned up, did anything get stuck under the throttle cable?
