The first thing to do is read your fault codes.

The 2.0 breather/throttle body/ICV clean up would be my first port of call.

3.0V6 engine only in the caterra...

I would give the idle valve a dam good clean out as a starter for ten.

Does it run ok with a little light throttle?

Other possibles are an air leak.
