Did that resolve the issue?
Have you replace the IACV gasket?
I was kind of hoping to get enough other stuff taken care of that it wouldn't set the misfire code. It doesn't bother me much but it won't pass inspection when the time comes. I may swap injectors around (only $6 for a set of o-rings) and see if that buys enough that it stops.If you know what you’re listening for, it’s not needed.
My 5.4 idles at 500 and I never thought twice about it. Maybe I should?
Certainly easier to pull apart a whole engine at home rather than standing in a junkyard pulling a head on an OHC engine. If it keeps the light out like this, I'm okay with it!I would not take heads off when junkyard motors are a dime a dozen...... 2001 thru 2011 are all interchangable. Its the 2000 and older that are hard to find.
Send the injectors to @Trav and he will clean them and get them perfect.Well bit of an update here. I'm sure I'll jinx myself.
Was towing about 2000 pounds to the dump with it. I pulled out in front of someone going a bit above the speed limit (at least 75 in a 55, I stopped accelerating at 75) and had to get on it. With 2000 pounds on a trailer. When I had to stop to scale in I thought the car stalled. Nope, idled smooth as glass. Went through the dump, drove into town and stopped at a few stoplights and I've never felt the idle so smooth. For the first time the light went out on its own, but did come back on.
Brought it up with a friend and he was thinking maybe the injector is bad and washing out the cylinder?
I decided to fix it the right way and dumped 3 cans of seafoam into 1/2 tank of gas (6x dosage recommendation) and drove it a ways on the highway with overdrive off. With how comically tall geared this car is that's only like 2000 RPM but still ...
Anyway, it went out again on its own after that and hasn't come back on. Idles at 575 RPM like it's supposed to and really smooth. Once in a while it will get rough -- rough now being more smooth than "good" was before -- but a tap of the gas brings it right back to smooth as glass.

I've found a few people parking out crown vics with the 4.6/4r70. The trans is year specific but the only change I know of on the PI heads was getting full threads for the spark plugs mid year 02. Same as my truck with the 5.4, I'd like to find a newer engine with the full threaded heads.
My truck is just about do for an engine. The 240K mile 5.4 is showing it's age. Econolines ran that engine up until 2015. Just need to find a low mileage wrecked econoline!
Here’s his info. I bought 6 used ones on eBay for my Jeep for him to do. 2 turned out to be bad, so if you do junkyard get some extras.Oh yeah? Wonder how much he charges. OE Injectors are $50 a pop. I could get a set of 8 from the local junkyard and send them out. Just gotta get the time to go to the junkyard.
Unless you're buying it from a dealership, there's a lot of counterfeits out there to watch out for, even on RockAuto. Trav was able to source me a set of 8 from Bosch and flow match them.Oh yeah?
