"WORK TRUCK DOWN"
I have a 2000 ford e250 van, 5.4, v8. 200k miles. Engine light came on & started idling rough when I sitting at red lights.
Took it to autozone and...p0171 & p0174 came up.
I changed the pcv valve and nothing changed. Got a smoke test & and saw a tiny amount from the egr (that's it), mechanic says that's nothing/that's not it.
He then sprayed something at or near the intake I guess, and it slightly changed the idling each time he sprayed.
Before I start handing out money...what do you think? PLEASE HELP!!.
