Common problem noticed on many car models.
Basically in this types of cases,you get steady check engine light on dash.The steady check engine light on dash is indication of error code stored in cars computer memory.
More than likely you have the beginning of an intake manifold gasket leaking. As this gets progressively worse the check engine light will illuminate and you will end up with cylinder misfire and a P0171 lean condition code. There is a new redesigned intake manifold gasket. This predominantly only happens when it is cold outside. This is easy to detect when you start the engine and when it is idling rough spray carburetor choke cleaner along the plastic manifold and the cylinder head surface. If its smooths out then you know is leaking. You also need to clean the mass airflow sensor. These are notorious for getting contamination on them. It will cause the vehicle to run extremely lean also.
