Didn't realise you had Evoscan... do a run and make it stumble lots of right turns, look at your logs and see if there is any weird/wonderful things happening at the same time as the stumble, ie voltage battery/alternator, o2 voltage (if narrowband or AF ratio if wideband) and so on. Never know. That's how I do a lot of my stuff anyway and tends to help if its a weird issue that isn't simply mechanical. My last one was random splutter and it turned out to be dodgy ecu earth strap.
Sucks about the pump though.
