My car listed above Tenacity model. I changed throttle body and MAP sensor but still doing the same. I found pine going to a container under right fender disconnected. Can it be a problem?

Hi,

You indicate pine going under the right fender. Do you mean pipe? Can you take a picture of it and upload it for me to see?

What to do is this: Have a helper start the vehicle while you check if there is any vacuum going to either end of the disconnected pipe. If there is, you have an engine vacuum leak which can cause stalling, rough idle and so on.

Regardless, let me know.
