This might not be running lean at all but just the oxy sensor saying so. Is the tail pipe black and are ther plugs sooted what ECU are you using stock or HP European version check the basics throttle switch fuel pressure both at ilde and at 2K pin test per Bentley timing at idle and total advance plus timing responce to the throttle opening check the vac advance and retard canisters for leaks compresion cold and hot the tesiting I did on the engine stand showed you had 180 PSI cranking with all the plugs out if you need a unfooled around with AFM let me know Robert Lilley spent alot of time and effort with the increased fuel pressure idea and I would think this would be a problem with cold starting starting due to the extra rich fuet miture I will CC this to him going faster miles an hour with the heat on Bob Donalds Boston Engine
