[s-cars] CEL/MIL light on/off occasionally, loss of power, codes....

Hey all,

For the last week or so, my car has illuminated the CEL/MIL light occasionally.  It would take 15-20 minutes, then would stay on for a minute or two, then go off...sometimes would come on again for a few seconds, then off the rest of the trip.  Sometimes it would reappear, sometimes it would not come on at all.  I only today lost some power, like the turbo wasn't spooling up.  So, I pulled the codes and got:

2113 Camshaft Position Sensor
2324 MAF (Mass Airflow) Sensor
2413 Mixture Adjustment
2222 Pressure Sensor Defective G71/Bad ECU

So, I know I have a small crack at the turbo side connection in my MAF/Turbo hose, but still holds pressure when pressure tested (I suspected that so I just pressurized the intake)...more air was coming out the oil cap than anywhere else.  Wondering where to look next....

BTW, the car was fitted with the wrong thermostat during a timing belt replacement, and I've been running a little cool on some really cold days this winter, or running while downhill on the passes.  I've already received the new thermostat and plan on replacing it this week...I've read that low running temp can cause rich mixture....possible reason for the 2413 code?

Also, please tell me I don't need a new ECU due to the 2222 code.....or that I need to crack it open....

Thanks all....and best regards,

Jim Fleischer
