HELP Truck idle problem

[hudsonfireman]

I have a 2001 F-250 4x4 7.3. It all started where it would not idle right and you would have to floor it to get it to go just a little. Found out the icp was leaking oil so I replaced that. Also dropped the fuel tank and cleaned it out and did the hutch mod, and installed an air dog system. I also replaced the fuel pump and the fuel filter/water seperator. Now it will start but does not idle to good if you leave it running it will die after about 2 or 3 minutes . If you try to drive it you have to rev it up in neutral then put it in gear and it just crawls then it will go and drive good at higher speeds. If you go to stop it will die. If you open the yellow tab on water seperator it will idle smoother. It does puff white smoke when I have to press on the throttle to crank it. CPS maybe I dont know. The service engine light is not on and the code reader I borrowed from a friend says it will not communicate with the truck. Only other mods are a DP tuner and a NAPA air filter.

Check your oil levels, id bet ya got an ipr going bad on ya, itd be great if you cold get a good scanner on it.

if you are cracking the yellow valve at the fuel filter housing and the engine runs smoother , you are getting compression into the fuel system, possibly bad o-ring on an injector or even a bad injector , ive seen this twice this year on a 7.3 , one was the tip on the end of a injector melted off , i hadnt seen that before , but truck was doing exact same thing , the other was the lower 2 o-rings damaged on an injector , customet kept driving until it had done enough damage to the injector that it was doing same thing also, so what im getting at is you probably will have to replace at least one injector ,really need to get some more diag done , but i think this is what is goin on here

Never thought of that or heard that yet, thats a good one to remember!

Thanks I will check on that next week after we see what happens with this storm.

Update.... I took my truck in to a mechanic shop and they ran test and told me my computer was telling one injector to stay open and at least one injector was bad. They said I needed to replace my computer and that Ford says if one injector was bad you needed to replace them all. About $5000 is what they told me..... ouch. Does this sound right? I am going to get a second opinion just to make sure.

[SCUFFY828]

sounds like bs to me , id replace the known 2 bad injectors and go from there

[Dirk]

Agreed. That's BS.

When I take it in for second opinion and if I have to replace 2 injectiors should I go ahead and do all 8? If so should I do stage 1? If so will all I have to do is reburn chip? Will it hurt transmission? Who to go with on injectors? Thanks for the help.
