Do you have an aftermarket intake without it being tuned in for the computer?

5.4L? If so you need to get a custom tune because thats why you are running lean. 4.6L your alright.

No, the computer need re-programmed for the intake and exhaust to not run lean. Head over to the Chips & Programmers section and ask questions. VMP tuning is good.

Disconnect battery and put stock intake back on to see if error goes away. If it does you will need a custom tune. 04s run lean from factory and some CAIs make it worse.
