What could be the most likely cause of a Ford PO174 code thank you
On what?
86 Lincoln Town Car (Galactica).
5.0 HO, CompCams XE258,Scorpion 1.72 roller rockers, 3.55 K code rear, tow package, BHPerformance ported E7 heads, Tmoss Explorer intake, 65mm throttle body, Hedman 1 5/8" headers, 2.5" dual exhaust, ASP underdrive pulley
91 Lincoln Mark VII LSC SE, triple black (Timewarp) - poly front bushings, KYB struts and shocks, Holley SystemMax1 lower intake, SilverFox AOD valve body,
1984 Lincoln Continental TurboDiesel - rolls coal
seems to be a lean code ( check for broken or disconnected vacuum lines ) but since I do not know what your working on this is the extent of any help I can offer.
2000 MGM LS Palm Beach Edition a work in progress
Here's a nice little write-up.

That said... could be a roached sensor, cracked exhaust manifold, loose manifold, loose downpipe, loose EGR pipe... Lots of stuff coming loose could cause that.
