I have not posted on here for a long time but still have my Noggy. It is currently running like a pig with multiple misfires detected on all cylinders but showing as intermitent.
Here is the list of fault codes can anyone tell me if the sensor faults would cause these misfires, I have replaced the plugs today and ordered a new MAF... Really need some help for my lovely car

17862 - Exhaust gas temperature sensor 1 (g235) short to ground P1454 intermittent
17866 - Exhaust gas temperature sensor 2 (g236) short to ground P1458 intermittent
17964 - charge pressure control negative deviation p1556 intermittent
17546 - fuel trim bank 2 (add) system too lean p1138
17544 - fuel trim bank 1 (add) system too lean p1138
Thanks
