Jimm 3/30/2014First step - have the stored fault codes or check engine light scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply as 'add answer' with the specific code for more assistance. There may be a fault code stored in the OBD memory which may not be displayed as a check engine light.
This step is a must - to minimize the cost.
Before replacing any parts and incurring any costs - the OBD (on-board diagnositc) system should be scanned - for free to retrieve any stored fault codes. Any local auto parts store can scan the stored codes - even if not displayed.
Then, post a reply with any codes for further assistance. As the next step - clean the mass air flow sensor with mass air flow sensor spray cleaner aerosol. Check these items; air filter, fuel filter, tire air pressure - check and rule out the basics before spending anything for replacement parts.
