He already did...

 

would after market 02 sensors cause the idle to do this?cause it has 2 new after market o2 sensors I got from advance they are not bosh they are ntk02 sensors just wondering?when I call advance they told me my truck has 4 02 sensors but the shop told me I only have 2?who is right?.advance told me my truck had ntk o2 sensors from new I don't know about that one I don't trust what advance says most of the time but does mopar make 02 sensors for my truck not sure or are they all after market?

 

NTK is the sensor most Mopar vehicles have from the factory. There could be 2 versions of your exhaust. My 07 has 4 O2 sensors, 1 in front of each cat very close to the manifolds and 1 ea behind the cats.

 

trucks with 4 sensors are california emissions vehicles.

trucks with 2 are for the rest of the non-CARB states...

Advance isn't exactly the best place to get information... I'm hoping they gave you the correct UPSTREAM O2 sensor.

 

truck fixed was a bad after market 02 sensor go figure had a 02 sensor put on from the dealer guess the after market ones are not that great?.not sure why the after market one did this but glad its fixed.

 

It happens sometimes.... sometimes people will soak a bad one in gasoline and clean it off so they can return the used one and get their money back....

Had it happen to me once too... really sucked.
