Welcome to the forum.
It doesn't sound good, perhaps post a video of the trouble.
The ticking can be many things, including but not limited to a motor knock, valvetrain out of adjustment, out of time and piston valve collision on one bank of cylinders. It could be as simple as a spark plug not threaded in. The ticking is not a good sign and means there is a mechanical thing going on, especially if its loud.
Are YOU going to work on the car, or is someone else? I would get this looked at ASAP.
Where do you live? maybe someone can suggest a good shop?
Lots of people are going to tell you to get the codes pulled, go to the auto parts store and ask for the code reader. plug it in under the dash board. We can give you a better idea if you let us know what the codes are.
