I did replace FEM , after all this time ~~~ I went around to dealers trying to flash the PCM early on in this hunt back in April and May . Currently, I am going to soldier the connections going to and from the accelerator.... These LS's are very delicate and fickle machine after all. I do know that I have been pushing this perverbial boulder up the mountain ,,,, trying to regain momentum for a departure away from my current circumstance. I will not in the future invest in or purchase a flood vehicle. Gentlemen , that is now an ingrained fact of my "Buyer Beware" vantage point ~~~ I was a bit excited and overwhelmed when I bought this car and , honestly no one, really helped me access the situation... 5 Months later and I'm trying to figure out the best way to sell her , for how much, and how I could be fortunate enough too purchase , the beautiful and seemingly trouble free car LS4 , referanced above !!! I've been over a barrel on this car more time than not, and I want you guys to all know, I apologize for bringing this " pain in the arse " scenario to you ..... I can only get on the internet every few days do too circumstance and after I conclude my response and update... I will go back under the steering wheel ! I do have NEW Motorcraft Plugs on the way and new coils ~~~ The Motorcraft, and various other coils that are now in the roulouete of my engine cycle I'm sure have not helped. My number one problem , as far as, what the car won't do .... IS ..... when I SHIFT into gear ~~ reverse or forward ... it stalls ~~~ so I back probed and found my shorts in the connector too the pedal ~~~ that is where Im at today ~~~ The car , starts, holds, but stalls in gear >>>> new MAF sensor, Differant o2 Sensors , And another day of determination..... The wiring too REM , seems new along with the wiring, PCM, the same, except for the support braciket that holds it , FEM < BRAND NEW ,,, (bc A Pillar hose was not connected and causing all the random mischief)... as far as the rest Joe..... I cant really say ~~~ Everything , HAS Worked fine in the past. I have been through the ringer on this one, Like never before.... And I do appreciate the vested interest, comradere, and responses I have gotten on this thread..... Its more than I can find from the neighbors out here (i.e. STICKS) Thank You ,,, Enjoy Your Day ~~~
