"engine" light stays on. Most of the time it runs fine. Often it idles roughly when stopped in "drive". It always starts quickly, but in a short time begin to idle roughly and eventually die. I can hold the gas pedal and keep it running. The problem is gradually getting worse. An Auto Zone diagnostic code readout gave the codes P0136, P0156, P1131, P1151, P0171, P0174, P0316, U1262 and B1318. Can you help? Thank you.
