Quote: "My friend says the ECU is learning and adjusting the engine settings all the time and getting the engine to fire and run probably reinstated/taught it, so realigning its settings." End quote.

I'm no expert on fuel injection but I would have thought that very unlikely. The ecu uses the map that is loaded on manufacture. Depending on the chip it may be that someone has loaded a different map or modified the existing map. The sensors (temperature, barometric, etc) are what feed the variable into the ecu. Good that you are getting to run better whatever.

jACK thanks for that.
Don't know if I can get "Sea Foam" in UK but I will get one of the proprietary fuel additives for cleaning injectors and put in the tank.
Not convinced the injectors are dirty as the engine runs really sweetly and goes like the proverbial. But adding it won't do any harm. I will also replace the fuel filter as a precautionary measure.
