Well, I spent a long time on the fuel filter and theres just no room to really work on it. I've pulled and pushed and twisted and did just about everything possible to it that I could. I even took it to a buddies garage where he could get under it and he couldn't get it off either. I've read that sometimes those little fittings just lock up and all you can do is pull it off completely (fitting and all) and replace the whole works. I'll do it eventually, as soon as I have the money.
As far as running rough... its never ran rough. Its always ran remarkably well. Infact, right now it runs as if its brand new. Sure wish it got better than ~13mpg though
The clunking I get is definitely from the frame. I suspect its those two missing nuts. I need to figure out what ones I have to get and get a few to put on.

You might be able to rotate the fuel tool slightly so the split contacts the "fingers" in the fuel line in a different place. There sometimes is a sweet spot that you have to hit.
If your truck is still running rough, it may be a bad coil. They sometimes become weak and it causes problems once the truck gets warm. Resistance should be between 4 and 10 kohms between the pins.
T-bird, these 5.4 engines have separate coils for each plugs. Your '99 probably had a 4.6 that has 2 coils that take care of 4 cylinders each. BTW, cool car !! |
