6.0 Misfire When Cold

Guys,
First I have read a lot of thread regarding this but always seems to have bad injectors.

I have AE, have done a buzz test and a balance test. Everything seems good but;
- Is there a way to make the engine not compensate for a bad injector, therefore not having a perfect straight line as I have.

- ICP Voltage is right at .25V
- IPR is like a squarewave, within autoenginuity range but..What is it supposed to look like?
-FICM Voltage gives me consistent 48V

Symptoms are just like the other guys - Starts perfect, runs a bit like a dog until warmed up, Jerk and misfire like crazy at coolant temp between 160-178, and after runs fine.


1- Is there a way to do a contribution Test without the engine compensating?
2- Could it be dirty EGR, EBP, Turbo.....

Give me some ideas,
Thanks
Dayz

Updates;

I believe it does it from time to time when hot, very random and not often.

Can Someone pin me in the right direction? Troubleshouting guide or post? How do you find an oil leak? Which injector is failing if any?

I have Autoenginuity and getting better with it.
Thanks
Dayz

Do a search for the word "stiction" there are a ton of threads on it and info on what you can do. I have had that issue for awhile now and have just been too lazy to do much about it because it runs like a champ 5 minutes down the road

Awesome thread on oil / cold start issues for 6.0 ----> http://www.powerstroke.org/forum/gen...ably-like.html

Mine started fine but ran rough for a few mins until it warmed up. I added Rev-x and it fixes the injector sictiation in a day or two. Now runs fine when cold. Search rev-x ALOT of people swear by it.

Only the IDS can turn off FICM compensation during a contribution test. Are you getting any codes?
