check to see if there is water in the oil if so you have a cracked head gasket or head

try disconnecting the battery for a couple of minutes so the electrical system reboots itself with a clean start. That might fix it. IU would give it 10 to 15 minutes disconnected before reconnecting and trying it. Further to that i would say take it to the dealer and send the bill to the place that did your oil change

The fuel pressure relay in the engine is not working or the fuel pressure relay is not working .
Try to replace the fuel pressure relay or soleniod in the engine area.

IF this does not work , Check the timing of the engine.

glad you solved it

Stop, DO NOT replace expensive parts or O2 sensor! Ford Explorer codes p0174 , p0401 , rough idle and check engine light on. First thoroughly check all of the hoses and elbows connected to the intake and EGR (vacuum system) for splits, cracks, holes or tears, this could quickly cause these codes and fixes for less than $10. Check all connectors and the EGR valve sensor it could have a crack as well, inspect thoroughly because a split sensor could appear attached to the vacuum hoses but hoses could just be sitting there not actually attached due to a split or crack. This was my problem replaced the EGR valve sensor and the two little vacuum hoses attached to them for $50-60 with in stock parts at the local parts store. Took less than 10 minutes to replace and is easily accessible, the check engine light turned off immediately without having to reset the codes by disconnecting the battery, idle became normal and fuel efficiency better. If you have THOROUGHLY inspected every hose, connector and elbow and found no issues, clean the MAF with electrical contact cleaner ( let dry) and clean the EGR with carbon cleaner. A dirty MAF or EGR could also cause these codes to pop up. If this still doesn't work, then consider replacing the EGR, if that isn't it then try the O2 sensor. Good luck!

sounds like something isn't hooked up right....
