Glad to be among Ford fans. I have an issue with my Excursion and would like to see if anyone could offer a suggestion or 2!
2000 Excursion 7.3 Limited 4x4 just under 245k miles.
This rig runs great, right up until last night. Started loosing power and running rough. I was able to run the RPM up enough to limp her home. Checked codes and got PO 720, PO 673 and P1316 I am running the SuperChips 1705 MAX Micro Tuner set on HP.
Thanks!

 

First off...
Welcome aboard!

Sorry to hear the rig is sick...

But that is typically how/why people find us.

Right off the bat...
Im going to point my fat fingers at the under valve cover harness that links the injectors/idm... and glow plugs/gpr.

They have a habbit of coming disconnected, pins burning out.

To address the issue you will need to get the cac tubes out of the way so you can pop the valve covers. Usually... if its a uvch issue at the connector... a simple squeeze on it to click it back in place does the trick. A lot of guys will recommend doing the 50 cent mod.

If you come on down to the 99-03 7.3 forum... The Brotherhood will be glad to get you sorted out.

Again...
Welcome to FTE!

Welcome to FTE, good luck figuring out your truck.

 

welcome to the site

 

Hi Sieggy and Welcome to FTE One of things you will have noticed is the folks here are a knowledgeable bunch and are always willing to help one of their fellow Ford owners out who may have a problem or question about their Ford.

As you have seen already in this thread, the information here is great. I am sure it will help get you pointed in the right direction.

Don't forget to join your local chapter and to upload some pics of your Excursion to your garage. Hope your enjoy the forums and we will see you in the threads!

 

Victory! Thanks for all the help here and from the other forums here on FTE. My 2000 Excursion is once again up, running great and reliable as ever. Here are my results:
I decided to take the drivers side valve cover off and check the connection on the valve cover gasket and sure enough it was ever so slightly gapped which was causing it to run great cool then after it warmed up the connector would seperate and run like a old John Deere "Poppin Johnny"! Upon further inspection the connector was partially melted so to be safe I decided to replace the Gasket and harness on both sides. I called my local Auto Zone to get a price and found out they had the Dorman brand set for around $72 which included the harness, valve cover gasket/connector and the exterior plug/pigtail. Dorman, however, is made in China so I decided just to be safe I went to my local Ford Dealer and bought the parts from them. My logic was, if the original lasted 242K miles then I wanted the same quality. Even at my jobber cost it was $278 so I spent a bit over $120 for dealer quality. Can you imagine my surprise when I opened the Motorcraft box pulled out the harness and there was a great big "Made in China" label on the wiring harness! Oh well, the quality looked good yet from now on, no more dealer if possible! After listening to the forums here, I only took off the turbo and air cleaner pipes and except for a bit of a challenge getting a couple of the valve cover bolts off everything went very smooth. She runs really well once again.
Thanks again to all here who's advice was very helpful. Now on to my son's 1999 Explorer project!

 

Good job! Welcome to the site and look forward to your other projects.
