does it improve when it gets warmed up?
Customer: replied 1 year ago.
No, runs the same warmed up. It throw a code about the FICM not running right. I researched and found that the original FICM was the wrong one for truck. I replaced it with correct one but, still running the same. I had both batteries tested and are good. Could it be a grounding issue? I noticed it does smoke white while giving gas and starts hard. when taking off it barely moves but, once RPM's come up it will go but runs rough.

It sounds like you may have a stuck EGR valve, also the FICM may need to be programmed with the correct calibration for your truck.

I pulled the EGR valve. it was plugged up solid. I cleaned it completely and re-installed(not to say that it's failing) but, didn't make a difference. I'm thinking it maybe as you mentioned, not calibrated for my truck. The garage said that it would not run at all if it need programming but, nothing about calibrations.

I have found that cleaning the EGR valve doesn't work,it seems like something happens inside and they don't work properly, also I would have the PMI process performed for the FICM.
Customer: replied 1 year ago.
The EGR cooler has been deleted already(prior to me).. Can I delete the EGR valve itself? Will this damage the engine at all?
Expert:  Ray M. replied 1 year ago.
If the truck has an EGR delete, then the valve isn't really doing anything other than keeping the check engine lite off. I would have the FICM programmed and then have them run an Enhanced power balance test as one or more injector may be defective.
