Ok, there are trouble codes stored in the computers memory, go to Advance or Auto Zone and have the codes read and post the code numbers and we can advise.
Replymaggie1027, May 31, 2013, 06:06Rookie
codes are P0171 and P0335

Have the Crankshaft Position Sensor checked/replaced, not DIY repair, behind timing belt cover, i think! May also have a vacuum leak.
