P0422 Three-way catalytic converter efficiency Intermittent Fault P1132 Front heated oxygen sensor (HO2S) Signal too high. Intermittent Fault The front sensor is the one in the downpipe, if this is giving mixed signals it will effect the fueling, replace it with a gen bosch item. I wouldnt worry about the cat untill you have sorted the lambda issue out. Did you use a gen bosch MAF or was it an ebay special?
