136000 500 After two visits to the dealership for MAF code P0102 they found that the plug/ wire had broken in the connector. After the MAF problem was resolved I was getting a code for the Valve Cam Position Sensor. 
136000 180 P0172 code for running rich. I am still chasing it down. Changed spark plugs and added fuel injector cleaner to the gas. Still reads code but light is out. It may be fuel filter/ pump or computer problem.

3720 0 ECM failure. Don't know why or how, probably just defective from the factory. Car threw a CEL and later, after 10 kms it started to sputter and rev at unusual idle levels and it was also in "limp" mode. Threw 9 codes at the dealer; they determined ECM 
27280 0 Mass absolute pressure sensor failure.... new part installed, no recurring problems. 
30380 4300 Weak valve springs happened twice.. 1st time under warranty, 2nd time was on my own bill but I upgraded to an entirely new upgraded head, so the problem will NOT return.
