The plug issues was supposedly fixed in 06, Ford decided to use Nickle antiseize on the plugs so there should be no worry. Also there are many options besides the Rotunda tool out. This has been a known problem for atleast 2 years. Lisle makes a tool that napa sells for $100 and you can even make one yourself if your crafty enough. I stopped by my dealer last week to get a wheel speed sensor and asked one of the techs about plugs on the 5.4. He laughed at me and said they are impossible. I replied bull**** and he said this dealer alone has had a 3% sucess rate. He also said that Ford just released a special cleaner to them about 3weeks ago. It's a chemical that they run through the system that breaks up the carbon.

Do you recall the name of that stuff???
Sounds like it might be something to try, if nothing else it's a "cleaner".

I wouldn't run E85 to save my life. Is your truck option'd from the factory to take E85?

That's like it is here, people don't realize there is ONE local E85 station, and the other is in Orlando. Wish I could monopolize the market like that.

yea but still no point in buying it, with the mileage difference, you loose money running it, i mean yeah it's renewable, but still...more $$ in my pocket is hat matters to me..

X2dac Yes it is a flex fuel truck. What is wrong with E85. My friend has a 06 and that is all he runs in it. The only problem I have is it gets about 2 miles less to the gallon.

Tinman

I really havn"t done the math yet so I really don't know the difference yet. Like I said around here in KY it is about 45 cents different a gallon and when reg was 4.00 a gal E85n was about 2.50. So who knows. I was wondering sence it is supposed to be more env. friendly is the carbon buildup less.

ford4wd08

well E85 still has gas in it, just not as much, so in a sense you will still get some carbon

Tinman

It also says in the manuel that you gain a little more horse power. At least I thought that is what I read... about 2-3 is what I have been told.

hell no it isnt.... the 5.4 has a $11 plug in every cylinder, and they break real easily.... the 4.6 is a breeze

Tinman

Yes some carbon but I was wondering if there is a difference from 87 oct. reg gas.
