2007 Lincoln Mark LT Stalls When Cold
 

Hi All! First time poster on this forum.

I have a 2007 Lincoln Mark LT with a 5.4 engine that was replaced app 16 months ago with a rebuilt one. Been operating great till about 2 months ago when I noticed that when I started it and ran it cold that it would stall or hesitate and then would sometimes go into fail safe mode and sometimes would say low oil pressure. No engine light comes on. I've replaced the oil pressure sensor and air filter as I've read on other forums that those could be the issues but not with mine. Could it be an oil pump? Any suggestions?? I'm probably going to have to bring it somewhere that can hook up a scanner and test it during a cold start.

I would hook a scanner to it. something is causing the oil pump to cause the low oil pressure
