2002 Excursion (V10)Vibrating & Missing

The other day when I started my truck up and it sounded like it kept missing. I was thinking maybe because it was early in the morning so I let it warm up. When I finally pulled off it sounded like I had a flat tire but I didn't. After acccelerating it stopped and then did it again. Can anyone give me any insight on what could be causing missing or the vibration? I almost forgot to mention that about a month ago I had my ball joints replaced by the Ford dealership.

thanks

Help Please!!!

As of today, if I am sitting in traffic, the truck is cutting out. It will start back up. I do not have the manual, but a orange light came on near fuel gauge. I checked the oil and put in 2 qrts. Not sure what this light is. Iy is also putting when I go up a hill.

I would appreciate any suggestions.

First, you need to tell us what light it is. Check page 10 in your owners manual. If you do not have a owners manual, you can download it for your truck:

Sounds like one or more of your Coil-On-Plugs pack is gone. That orange light is your check engine light. I'm sure it has detected a misfire.

It may not be the COP. It could be a bad injector(s), loose wires or a bad sensor somewhere. Go get the computer scanned for trouble codes and begin from there.

I took it to the Auto Parts store and connected the scanner to the computer. I got codes P0720 Output Speed Sensor circuit malfunction and P0309 Cylinder 9 misfire detected.

Is this anything that I can repair myself?

Thanks for all the help so far.

Replace the #9 COP. You should be able to get that at any reputable auto parts store. It is fairly easy to replace with basic hand tools. Get a new boot, too!

Replace that and then see if the Check Engine light and drivability problems go away. If not and the P0720 code still comes up, then I would suspect the Vehicle Speed Sensor on top of the rear differential. That, too, is easy and cheap to replace on your own.

Let us know how you make out and don't hesitiate to post up any questions concerning your repair.
