I found out that it has exhaust leaks on both sides of the motor. looks like the fork trucks at the auction damaged the flexible connectors after the cats.
That is the first [place I would look on a older car.
But this car is drive by wire. No TPS
Just has a Accelerator position sensor and the throttle body internals.
Any one have a code scanner that shows data (pids) willing to look at something for me?
I need a 5.7 hemi drive by wire owner to look at a few pids for me to see if what I have is normal or if my Pedal sensor is bad..
The pedal has 2 sensors one reads say 14.6 at idle and the other reads about half of the first say 7.3 but the second sensor reads 0 then 7.3 then 0 this is with out pressing the pedal at all.
Im thinking this reading might be why my the idle goes up and down, because the sensor it reading up and down.
But I cant find anywhere how to test the pedal or if this is normal or not.
If it was a cheap part I would get it just to see but its like $150-250
Hmmm... Have you tried any type of cleaner just in case? What RPMs does it idle at when in drive. Can you adjust the throttle control thingy like on older cars? When my cars egr made me start stalling out my dad would adjust something with the screwdriver and it would send more fuel in and idle higher...
Check the coil packs are working correctly.

thisis is what i found real quick, have a local muffler shop weld the openings on the exhaust just in case shouldnt be that much and give this thread a look, use the search option at top of page, ill keep looking as well.
Just watched your video and you have either a major vacuum leak, or that engine has an aftermarket camshaft and needs a custom tune...Can you please hook up a vacuum gauge and post of a video of the gauge...I could tell you ASAP which one is going on
I am betting you have a vaccum leak..or a slightly larger camshaft that needs more fuel at idle. I am confident that the motor is healthy, just need to determine if the intake and vaccum lines are sealed, if so time to look at the possibility of a camshaft and missing custom tune. Best guess is a leak
