Mutliple codes

[wyodan59]

I recently had some issues with this van. I had the codes checked and came up with 7
P2187 System too lean at idle Bank 1
P0101 Mass or Volume air flow circuit range/performance
P0300 Random multiple misfire detected. This one made mil light blink until restarted.
P0160 Oxygen sensor circuit No activity detected bank 2 sensor 2
P0174 Bank 2 System too lean
P0133 Oxygen sensor slow response bank 1 sensor 1
P0171 Bank 1 system too lean

What Is going on? Is it time to rid myself of this van or what? Is there anywhere to get repair fix information on KIA? Everywhere I go they say NOT SUPPORTED. This is frustrating me!

I purchased A new code reader for my smart phone. I has code connect with it. The MAF code was a badly worn out air intake tube. many cracks in it. This seems to be a common problem. Once changed that code went away. The missfires were O2 sensors. Bank 1 sensor 1 and bank2 sensor 1. once changed the miss fire code went away and the van has been running fine. code connect is a wonderful thing to have at hand. This forum is of no help. seems to be plenty of people looking and no reply's. I am posting this in hopes that this information will help someone in the future.
