knock sensor / intake manifold

Hi, this is my first post. I believe(hope) its just a faulty knock sensor. I have a 1998 expedition 5.4L. I will go have trouble codes checked tomorrow when I pick my daughters up from grandmas.

From what I gather, the sensor is under the manifold and is labor intensive. I cannot afford to pay labor so I will do it myself. I have done basic repairs, brakes, water pump, radiator, t stats, heater cores, etc. But nothing deep into the engine like the manifold. I will be doing this at night while the kiddies sleep and won't really have time to make mistakes.

Any pics, diagrams, step by step instructions, tips and tricks would be greatly appreciated!

Would it be the same procedure for a f150? Wondering if I should post there too?

Well I had them hook up the scan tool and it wasn't throwing any codes. I guess I didn't luck out and have it be the sensor.

Why don't you start from the beginning and tell us what's wrong and what the symptoms are that led you to believe it was a knock sensor.

I started a new thread about it.

Engine knock at only 114,000 miles?

Thanks!
