Truck runs! Fingers crossed

Truck runs up and idles at 1400 RPM's now. Touchin the brake drops it but then raises once I let go

What tune are you running? I know when the exhaust sensors are unhooked it will cause a high idle condition if not written out of the tuning. For sh!ts and giggles try plugging the DPF sensors in and see if the idle comes down. There may just be an issue with the tune.

Switching tunes right now, it was on street, putting it in extreme street

Check the gate lock connectors on top of the left coil bucket. I've had bad connections there before causing elevated idle situation.

Good idea, might want to look for a bent pin in there too.

Truck won't start again, ***kkkk

I have successfully passed my "SH!T LUCK" onto you..... Maybe my rig will run again soon...

Out of curiosity what is your RP at during idle before it ramps up ?

 

[extreme3807]

Put it on extreme mild and it ran. Still have high idle. At idle the Livewire reads 35.00 FRP, when it high idles at 1400 it reads 43.00

 

[extreme3807]

I also don't have any CEL with extreme mild from the 4R

 

[extreme3807]

Cleared codes with the truck running. Idle went back down to 700 RPM's, still no CEL.

 

[SEABEE08FX4]

Weird, sounds like an electrical gremlin possible PCM glitch from all the changes and somethings that used to communicate together than no longer can might be tripping things up.

 

[extreme3807]

Exactly what I think it is. Only tune it will start on is extreme mild. It will high idles but all I have to do is reset the codes at idle and the idle drops back down. Starts everytime now, weird

Have you contacted eric? Whatevers different on x mild from the others might lead him to a solution.

Can you clear just one code at a time or no? If you can do just one at a time untill the idle goes down and you will know where the issue exists.

 

[extreme3807]

I can't clear one code at a time. The codes that are pulled up when I clear them stay after I clear them. Pressing the clear DTC button with the truck running is the only way to bring the idle down. I'm gonna call Eric tomorrow

 

[powerstroked08]

He should be able to get you fixed up. Good luck man. Any luck with that ground?

 

[extreme3807]

Haven't tried it yet, been battling this computer issue. It's the weirdest thing I have seen. I can actually get cruise control and no CEL with the 4R, WTF?!?!

WHOA! That thing has a mind of its own! A 4R with cruise your truck truely is special.
