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.
- 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
Other than the idle, truck seems to run fine at WOT and gets up to speed easy.
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?
