I dunno where it would get the two water temp readings, there's only one sender for the ecu 
it is worth checking the plugs as they are a consumable item, they do wear out eventually and a set of NGK's would be £6 or so at the most.
cheap cats are notorious for causing issues like these btw, often need to get them roasting to get a pass and often they barely do and never last more than a year, you really dont want to be buying a genuine item btw, worth more than the car, though if you can find one that hasn't been weighed in yet then an used o.e unit should be good.
