Yes within 20,000 miles. Aftermarket one of the auto part stores. Maybe that’s my problem
so the Denso didn’t thro a light until now it’s throwing codes 135 an 141 an messing with the acceleration so I am currently running with it unplugged again

 

You aren't getting power to the O2 sensor heater circuits. Whip out the wiring diagrams, see if they both draw power from the same spot. As both of them are whining about it, it *should* be easy to find.

Replace the IAC with a mopar unit. I bet that solves it. (clean the throttle body as well, reset the pcm, when it's all back together, turn the ignition on, count to ten, THEN start the truck. Don't touch anything else.)

 

I have looked in the wiring diagram an the only thing these sensors have in common other than the pcm is that they share a ground also there are both connected to the automatic shut down relay. Could that be causing them to act up?
i will double check the ground when I get back under there.

 

ASD relay also powers the coil, and injectors, so, if that was the problem, the engine simply wouldn't run. Problem has to be further downstream.

 

So I am currently running with my o2 plugged in me an a buddy we’re trying to log some data kinda just messing around seeing what came up on his hand held scanner tool. An the truck seems to run great I do suspect it to be the idle air control unit.

I believe the beginning of my o2 sensor issue was simply the truck didn’t like the first ones I put in. It seems to only have an issue when I need it to idle in Park or neutral an if it does start idiling weird I pop it into drive an it seems to do fine. An it will die if I let it but it throws no code while doing so.

So I was able to print off the data from the truck while it was having this idiling issue. Is anyone on the forum able to look at the data an see if they can maybe confirm or see any other issues. I simply have no idea how to understand what I’m looking at.
The photos uploaded in the wrong order but the rough idle started around frame 11 to 15

 

I note that map drops off significantly, even though engine load, and RPM don't change that much....... Check the little rubber elbow that feeds the map vacuum. See if it is clogged, or just dried out, and leaking.
