Injector or the fuel pressure regulator is leaking also the coolant temperature sensor locked up on the open loop mode demanding fuel when not needed.

I tried different fuel pressure regulator and changed the whole fuel rail including injectors. Didnt know about trying the coolant regulator sensor. Its only the #1, 3 and 6 cylinders (those to the firewall side) so I was thinking of something pertaining to those three. Thanks for the info. If possible can you explain how can this coolant sensor cause this to those three alone please. Thanks again for the info I will try this and see.

The CTS will not only affect 3 cylinders it has to be common with the 3, could be an injector driver staying open then is suppose to be -Check for vacuum leak on that side
