runs slow. any acceleration makes it slip. only gradual go

First look shows a slick scene under the hood. Looks clean and organized. Note that everything is hiding under something else. Don't think for a minute that you can access any part besides dipsticks and pour holes without removing multiple parts to gain access. You have to remove the plenum manifold just to change the spark plugs. This is a very time consuming and heavy technical process. Most vehicles; plug change in 45 min. to an hour. This one; get all your tools out. I don't have to tell you what you already know. 2 to 3 hours for those who do it every day. For ME; at 60 I did it in 7.5 hours. This is not a good time frame for these tasks. Looks like poor planning to me. You may need to check with engineering to see where they screwed it up. Don't ask me what I think about this vehicle. Tell me how I can make it serve me for a few more years. Least you could do short of lawsuit. I know were I'm at. Your dime to change my mind. Who has the biggest balls? Waiting for your reply.
