I was having the hesitation issue on my 03 Ram Quad 5.9. O2 code
I replaced the upstream O2 sensor with a Bosch part and it worked great for about 2 weeks.
Now the hesitation is back.
After reading here that Bosch and Dodge don't play well together .
I need to know what manufacturer to use. The dealer just told me they just replace it they don't know what brand it it.
Would I be correct that since the plugs were NGKs that the sensor would be also. Thanks

 

Ma's favourite brand of O2 is NTK. It is the only brand I will ever use. Boshe anything other than my washer and dryer is something I run away from.

 

That is what I am finding out the hard way. Thanks

 

Use the OEM sensors from dodge.

 

Dodge uses rebranded NTK as their OEM's.
