NTK O2 PN Info...
I am under a time deadline and cannot spend today searching for my correct PNs and all that. Normally I am a big boy on the Internet and can Google and research and read up all on my own.
But not today.
Here is what I need a hand with.
I have the 4.0L with FOUR O2 sensors. It is a 2003 Sport. The replacements I paid an arm and a leg to have the dealership install for me are all four probably Bosch. They are unmarked, but the parts guy was pretty sure that with DC involved that the current supplier of the supposed OE parts would not be NTK at all these days. They would almost certainly be supplied to Jeep by Bosch.
I need these OUT of my jeep. They are the only thing left that could be continuing to throw P0171 and P0174 lean condition codes.
I am sure it is the sensors that are pissing off my computer and that there is actually no lean condition extant.
So, do I have to replace all four *again* or both upstream ones, or just one of the upstream ones?
And by upstream, you guys mean the ones physically located higher up on the block, correct? Stupid question, but I need to know to prevent some further stupidity that actually costs me time and money. (The dumb question is free!)
Further, I want to order these tonight! I assume that rockauto.com is the place to get them. But which part numbers do I order?
And there is some sort of WF discount code, too. Correct?
I have pulled and cleaned everything. I have replaced the entire CAI intake that came on this heep with an OE box and tubes. I have checked everything recommended to me here on WF. The last bit is the suspect O2 sensors. So that has to be the source of the codes.
Any help/hand holding/training wheel-type of assistance would be greatly appreciated since I am about to go offline for the next 12 hours or so.
