O2 sensor Question
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
