Just read up on a recall for EBP sensor and connector

If there is no change in manifold air pressure, when the PCM opens the EGR valve, disconnect the vacuum line from the EGR. Then connect the handheld vacuum pump directly to the EGR. Next, start your vehicle’s engine and run at idle. Slowly apply the vacuum to the EGR valve by pumping the hand held pump. If the EGR opens and the engine does not stall, then you know that the EGR passages are clogged and need to be cleared. you replaced the valve already but did you clean out the passages that it mounts to?

Ask Your Own Ford Question

this has nothing to do with your fault code

Ask Your Own Ford Question

there are fault codes and TSB's for those fault codes for a reason. if the EBT is not faulting then its not the problem

Ask Your Own Ford Question

I'm recommending a reprogramming of the PCM. I'm not just "sending" you to a dealer

Ask Your Own Ford Question

Ill let someone else chime in on this. Good luck

Have it booked in for tues
In the meantime I disconnected the egr connector and in acts up less
The ford service guy was hesitant on the update fixing the issues

Y​es you are correct, I seriously doubt the PCM reflash will fix this concern, since that TSB came out in 05', I can only suspect you already have the latest calibration in your PCM already. I would believe you have a either a wire problem to the EGR throttle plate, or a bad throttle plate itself. Here is the location. Click here

I disconnected throttle plate as suggested and it solved my problems
I had the egr unplugged as well before
What do I need to replace to fix my issue or is it safe to just leave it unplugged as I wish to keep this truck long term

I​ have seen them unplugged with no problems, or you can unbolt the throttle plate and replace, there is no programming necessary on this part replacement.

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.
