2004 Ford Excursion, Shifted gear no power

[saranay]

Before the problem started, my engine was having this Water/Fuel light came on for a few days. Which was causing my engine to run inconstant and then sometime stalls at idle. Check

When the gear is shifted on P or N, the engine is running at idle and responded to a gas pedal just fine.
When shifted to R or D 3/2/1, It moves on at idle speed, but doesn't responded to a gas pedal. I have to press the gas all the way down for awhile for it to accelerate up very slow for the engine run up above 2000rpms to get a 25mph speed.

So today I decided to get my transmission flushed out and replaced a new external filter. Then I removed the transmission pan to see if anything is burning out.

The truck is running and is moving when shifted gear at idle speed. No pulling power when pressed on gas or slow acceleration at high idle.


Any idea please help?

Did you have codes?

[saranay]

It showed several Injector Circuit codes before I have drained out water seperator and reset the ECM. Now all the Injector Circuit codes are gone.

Checked with OBD II again, it only shows P1000 Powertrain "Monitor Testing Not Complete". I think because of the OBD II.

Had my transmission flushed and remove the pan. There is no particle in the transmission pan.

Am going to try to remove and clean out my all Injectors and Regulated return fuel lines to see that will resolve the issue. See if that has to do with the sensor

I will keep update again.

*Update Fixed*

I pulled out all the fuel system (Injectors, Fuel pump/frame, Fuel tank inside out) and cleaned with a gallon of Simple Green. Disassemble fuel fame and pump out, use simple green and high pressure wash clean it.

Soaked half way in Simple Green for 2-3 hours. no need to scrub or wipe down.


>> TIP FOR EVERYONE:
Because I purchased an after market fuel filter from Autozone, I had to remove a metal clip inside the spring out from fuel pump to get it fit in smoothly.
