What year? how many km's on your car?
Have you checked your cat converter? Cleaned your air filter and MAF sensor?

check the cat. Probably clogged.
If it's fine, then you probably have low compression...
Could be other things, but there are a lot of issues that cause these types of symptoms, and it's difficult to diagnose over the internet.

I think the rest of the post ensure continuity on that portion... Haha


But yeah, like others said, check your cat. If it glows red hot after a run, it's probably clogged. If not, your engine could be toast.
