I normally read the forums for info, this is my first post. I have 2004 F250, has new oil cooler and EGR delete. 2 weeks ago, I had to have my truck towed due to not knowing what was wrong with it, ended up being wheel baring, had that replaced, got truck back, seemed fine, drove it for a week and when I was leaving work, seemed I had no power, I knew I wasn't going to be able to make it home, pulled off and called a friend to pick me up. He looked at it, we decided to take to my work and look at it, had a hole in a boot that connected turbo to something(sorry, I don't know much about engines, but learning more and more) ordered the part, they put it on, still seemed to choke and had no power, they unhooked something, maybe air intake sensor??? and was fine. The next day, got in truck, no power. I told them thought was FICM. Checked FICM, was 46v cold and when turned truck on dropped to 24v, got new FICM, put that in and truck runs and sounds amazing!! The next day as going to work, I notice a real bad vibration, shakes, almost felt like losing power, noticed it only did it when speed was about 50MPH and about 1600-1700RPM. If I let up on the gas pedal, it will stop or if I got on the pedal, would be fine, just regular cruising speed around town, and mainly notice it on the road to and from work. I don't know if this is an injector problem, transmission, turbo, tires, etc...any ideas? I'm sorry this is long and I don't know technical terms, if anybody needs more info or questions, I will try to explain. We were going to test the injectors, but don't even know what to look for (:

 

One easy test.
Reach under the FICM and make sure that the plugs are all locked in.
They can be a bear some times (well most times). next thing is do you
have some gauges like the Compare the Features of the ScanGauge products : Linear Logic
You want the ScanGaugeII : Linear Logic - Home of the ScanGauge it is good
for most of the basic stuff. If you need more then something like the AE
with the Ford bundle is an option

Autoenginuity Scan Tool
PLUS This
Ford-family (EI01)
And there will not be much you can't do
AND Yes it's on my with list. But for now it's my SGII and my Snap-on Solus
scanner. The Snap-on will di it but I need to upgrade to the tune of $1100
if I want all the NEW added features and the AE will do a lot for a lot less.
