You too can become the master of ODB! Just go to Amazon and buy a Bluetooth to ODBII adapter. You can use your smart phone and read the codes. Amazon.com: Vgate Bluetooth Scan Tool OBD2 OBDII Scanner for TORQUE APP ANDROID: Automotive

No smart phone, try this: http://www.amazon.com/Autel-MaxiScan-MS300-Diagnostic-Vehicles/dp/B001LHVOVK/ref=sr_1_5?ie=UTF8&qid=1426157848&sr=8-5&keywords=odb

You can go to a parts store and sometimes they can read the codes for you. You can use the search function in the upper right and get all sorts of cool info.

We need more information to help you. Today's engines use computer codes to describe their issues. Until we have the codes, we can't help you. So get the codes, look them up and then we can offer more.
