Strange Ecu Reading

Started the car in mode 2 and left sensor reading is fine (more than 5/per 10 sec) The r/h sensor doesn't show any led.The general check showed code55.Car is running lumpy on idle and low revs but on drive going well although not boosting much past .7.I have new Lambda sensors fitted. Any guesses as to what this could be ?Just started cleaning up coil packs etc and going to swap MAS and PTU to eliminate them .Car has had engine out ,engine in recently..........All knowledge gratefully absorbed :D

    Unplug and reconnect the RH sensor - should hopefully clear the problem :) You sure the vac hoses were all replaced correctly when the engine was replaced?

    Cheers Andy,the sensor is so difficult to reach now as it rides on the back of the wastegate,but I will try to get to it and do that .I will also ask my mechanic to look over the vac hoses. Is there anything else it could be?

    Connector is mounted on the RHS of the plenum - grey plug, 3 wires ;)

    I disconnected the sensor at the connector and linked it back up again and its still the same..no reading?? Tried swapping the MAF from another Z and this seemed to change the way the car runs (smooths it out)still need to test further but it looks like this may be the culprit...does this sound likely to you?
