I just bought my 2005 Dodge Dakota 4.7 couple months ago and I have been going through it to make it a little reliable truck when I need to haul stuff in the bed.
I am noticing somewhat of a rough idle after the truck comes up to warm temps, before that it idles fine. The truck doesn't throw any CEL's or stall, I can just feel it when sitting at a light (regardless if in drive or neutral). I have done the following since I got the truck few months ago.
Other than the idle, truck seems to run fine at WOT and gets up to speed easy.
- Changed Oil/Filter
- Flushed Coolant
- Replaced Sparkplugs (NGK V-Power Copper top, gapped to 0.040)
- Replaced Evap Solenoid
- Seafoam cleaning through intake.
- Fully cleaned throttlebody.
- Smoke Tested (No leaks detected)
- Replaced EGR Valve
The only thing that I am noticing is that on 02 Bank 1 Sensor 1, it looks very jaggedy while 02 on Bank 2 Sensor 1 looks smooth. Here is the picture.
Could I have a 02 Sensor that is going out?

It could be an o2 sensor it could be the coolant sensors check to make sure the temp and the sensor match. With o2 sensors the dodges are sensitive I believe Mopar or ngk don't use the cheap knock offs.
