Codes for 2.2 Petrol engine are here http://www.omegaowners.com/forum/index.php?topic=90576.0

P0130   O2 Sensor 1 Circuit Voltage Low 
P0170   Rich Exhaust 
P0170   Lean Exhaust
P1405   Exhaust Gas Recirculation (EGR) Valve Feedback Voltage High
P1405   Exhaust Gas Recirculation (EGR) Valve Feedback Voltage Low
P1405   Feedbacksensor Exhaust Gas Recirculation
P1555   Throttle Position Sensor (TPS) Load Signal not Plausible with Engine Load

The 2.2 has a reputation for bringing up lots of codes and distracting the inexperienced from the true fault

Without access to a suitable code reader (and on a Sunday afternoon) I would start by cleaning the EGR valve. http://www.omegaowners.com/forum/index.php?topic=90553.0
