I have an 2005 5.4 This thing is guzzling fuel almost as fast as i can fill the tank. got codes scanned and it indicated i needed new O2 sensors I changed air filter replaced upstream O2 sensors on sat. Disconnected battery cables and engine light stayed on Drove to work this morning and the truck is still sucking fuel like crazy I went back to auto zone and got codes 2195 2196 2197 2198 all indicate bad upstream os sensors but i just replaced them three days ago I also cleaned the MAF sensor work has been very slow and I dont have alot of money to keep throwing at it blindly or dumping in the tank any advice would be appreciated

 

Take it to a Ford dealer and have them check the injectors.....
They should be under warranty but check the letter.....this is only for 2005 5.4 3v.....

I was afraid someone was gonna throw out the D (dealer) word If you think thats the way to go Ill schedule it But the D word is almost always Accompanied by dollar signs way over 100,000 dont think anythings coverd but if you think thats it ill try

 

Some more things to try....
Clean the MAF and TB.
And reset by disconnecting the battery then turn on your lights for 5-10 min.
If that doesn't help you'll need to find someone with a SCAN TOOL not a CODE READER.

 

You better get those injectors checked! Could be a sticking trottle body, but I would not take a chance on the injectors. You can hydreolock and destroy the engine.

 

Wasn't a TSB / Warranty extension letter sent out for this? I received one for my 2005.


EDIT: Just read 88's post.

 

Pay The dealer and fix it your self or keep guessing and wast mor money overall
