Hello guys and gals hope everyone is well. Back again with an update and some questions. Soooooo for the update 2001 Durango slt 4x4 with the 4.7 and approximately 265000 million. I was chasing a rough idle and occasional stall. I replaced coils upgraded to 4 hole injectors new 02 sensors and a few tps also breathe factmuffler with a flotech raptor. I still have the same symptoms and even after installing 02 spacer I am getting a bank 1 to rich code my question after all of that is I have another 2001 4.7 Durango but it isn't 4x4 and doesn't have the security sy that the 4x4 does will the pcm from the 2wd work in the 4x4 ? This tag is under the hood of my 4x4 and it has a salvage title

I have also installed 2in lift shackles and since the mods throttle response is awesome and power is up a little

 

Have you ever replaced the IAC valve? Did you use Mopar TPS? New plugs?

"265000 million".... you sure? I thought I had a lot of miles.

 

Lol sorry 265000 miles and yes new plugs and I replace the iac I tried several lower cost tps to no avail and nite the bullet and got one from dodge at over$150.00 the pcm is all that's left. When it stalls it's like all power is gone for about 10 seconds then it normal

 

Did you compression check everything? Have you tested fuel pressure?
