2000 Ford f-150 5.4L fuel rail symptom, little help?
The right side fuel rail is making a noise. tap tap tap. I can even feel it when I touch it. The other side is just fine, no tap, no noise. As a result, the motor runs like crud and keeps throwing "lean fuel right side" and "misfire no.1 cyl." codes. What's doing this? Gotta know cuz I need this truck soon and am too broke to put it into the shop.
Thx.
I thought so too. New plug, coil and injector. Problem still there.
Bad cat would give me misfires up and down the bank.

it's kind of normal, but if it bothers you, get a new fuel pressure regulator, that might stop it..

Sounds like the making of a faulty injector.
That is what the lean code and misfire seem to point at.
