Check engine light came on the other day and it turned out to be a common fault: Stuck secondary injection pump which pushes air into the manifold during cold start as part of emissions controls. The pump can get stuck on and cause all kinds of problems with the fuel-air-exhaust continuum. A friend who does my engine maps deleted the pump from the ECU programming and we disconnected the pump. Job done.
