I have called all the usual places (Autozone, Napa, etc.), searched the whole internet, called dealerships, called used auto parts places, called Ford, and still no joy. Everyone says this part is discontinued, there is no replacement, and no one has it. I can find this part for the 5.4L all day long, but not the 4.6L. It's part # 2L1E-9F775-AA. Any suggestions?

I'm having issues with bank 1 and 2 running rich and having rough cycling idle and can smell the rich condition. I just picked this thing up and bought it with both rich codes. So far I've replaced the EGR and EGR line, MAF, intake temp sensor, plugs, coils, fuel filter, purge valve, and egr pressure feedback sensor.

Still having issues with the rough cycling idle and rich condition. I'd like to go ahead and change the PCV valve and regulator, but can't seem to find matching parts.

mine looks like this: https://www.ebay.com/itm/For-2002-2...554979?hash=item5b4c812123:g:sQcAAOSwiBBdPmDH but... says it for the 5.4 and not the 4.6 would this work?

Is the diaphragm of the dampener ruptured? It'll suck raw gas in through the vacuum tube if it is, and that'll give you what you describe for sure. Take the vacuum line off it and plug it, and see if your rich condition goes away. But if the dampener's diaphragm is ruptured you probably see fuel come out of it. If yours looks like that use it. They're just there to dampen rail fuel pressure pulses, they are not the main pressure regulator ( that's on the fuel pump assembly...).

Dan in TX,

Dick in TX here.

By chance do you recall the measurements in 'live data' from scan tool? Or was it just rough running that directed you to the part?

Thanks
