Hi,
That could be caused by a few things. I need confirmation that it is a 1.8L gasoline engine. Is that correct?
If so, first, see if there are any major vacuum leaks.
Here is a link that explains how that is done:

Next, I need to know if the check engine light stays on while the engine is running. Additionally, once off an idle, does the engine perform as it should?
Let me know.
Joe
