First off powerhead has been replaced. Rebuilt lift pump and high pressure pump also seized up so it was replaced. Also idle stabalizer has been disconnected. Motor has ran good for almost a year. Now motor will start up and idle fine and sometimes it will come out of the hole and run great. Other times it acts like it is loading up and running very rich. Will not come out of the hole. Checked fuel pressure at low pressure pump and checked high pressure pump and both checked good. Went ahead and checked ignition system to elminate that. Stator and trigger checked good and timing advance seems good. Checked temp sender with a ohm meter and seems good. Any advice or direction would be great.
