Hey guys, haven't posted on here in a long time. But unfortunately I'm having some issues.
Car: 2006 Lincoln LS V8
I have had the P0108 code (bad EGR) for the past year or 2 and have just driven it regardless since it ran fine anyways. Then I moved to Wisconsin and I am now required to pass an emissions test which they will not even perform if I have a CEL. So I bought the OEM Motorcraft EGR valve and when I was taking the old one out, I pulled a rookie move and snapped the spigot off of the nearby fuel pressure sensor. So I ordered up the cheapest non-OEM fuel pressure sensor on eBay I could find and threw it in there too. I finished the job last night, started it up and took a half hour drive and she ran better than ever. The slight shake at idle that I had grown used to was gone. I cleared the CEL before I left and it never came on once during the drive.
Today I drove to work and even came home for lunch and it was still running perfectly. However, after work today I started it up and it didn't fire up like it usually did. I cranked it again and it stumbled a bit and started idling, but the roughest I've ever heard it idle with RPM fluctuating between 400-700. I barely made it home without the car dying (I live 4 minutes away from work). Here is a video of the idle when I got home: today:
My initial thought is that I bought a junk fuel pressure sensor and it has already failed, hence the engine running fine for the first hour of operation. Keep in mind that despite a bad coil, this engine has run strong for the 40,000 miles I've put on it. In my opinion, it would be way too big of a coincidence for the issue to be unrelated to the EGR valve or fuel pressure sensor. Anybody have any other input on what may be wrong?
Thanks in advance.
EDIT: I also forgot to mention that the car was smoking and reeked of fuel that I could smell even from inside the cabin.
