Yeah thats what I'm gonna do.I only use OEM parts for all my ignition repairs since they seem to work well in the Hemi's.Izero got it covered pretty good but I'll give ya a little more detail WilldikeM66.Bank 1 is your drivers side since cylinders 1,3,5 and 7 are on that side and they use cylinder 1 as a reference point.The O2 sensor in front of the catalytic converter on that side is sensor 1 or S1 as it's commonly called.The o2 sensor behind the cat. is sensor 2 or S2.Your passenger side has cylinders 2,4,6,8 so hence "bank 2".The O2 sensors work the same there.So if someone says to you "B1S2 (bank 1 sensor 2) it would be your driver side O2 sensor that is behind the cat. converter.

 

OK......heres my plan for those interested.I just sent an order to rockauto.com and bought 16 plugs and 1 O2 upstream sensor (I was gonna get 2 but they only had one in stock).I did just put new plugs in not long ago which is the good news.The bad news is I believe I used autolites,which aren't the greatest.I did so bcuz they were on sale at Advanced.So they're gettin pulled out and replaced with Champion coppers.I shoulda done that to begin with but coulda,woulda shoulda.........As for the sensor,since I could only get one upstream right now without having to wait,I'm gonna put it in B1S1.If I still get the misfire,I'm gonna pull it out,put the old one back in since I will know it wasn't the problem.I'll move the new one to B2S1 and see what that does.If I'm still get the misfire thing,I'll buy a downstream sensor and move that around and see what happens.If none of that solves anything,I'll start with other sensors.I'll buy the TPS first and go from there since thats a likely culprit if it's not O2 related.Lemme ask ya'll a question though.The Champs are gonna come gapped at .044 but OEM is .045 Does that .001 make a big difference?

 

In my experience .001 doesn't make that much of a difference and since they are copper you can gap them pretty easy so you might as well just take the time and adjust it that little thousandth of an inch.

I would also like to let you know that the downstream O2 sensors have NO affect on the fuel and/or timing system in your vehicle, the only thing they do is tell the computer if the Cats are working properly, which is just to satisfy a ridiculous EPA requirement from the clean air act... so no sense in spending the $ unless you throw a code for CAT efficiency.

Let us know how the Coppers turn out.

 

At SCRam I know what and how the o2s work very well just wasnt sure what b1s1 was never seen it that way. And im with Izero your post cat o2s dont trim the fuel or air.

 

Which part number did you order for the plug? I was about to order today or tomorrow until I saw you say they only have 1.

 

I mean for the 02 sensor...not the spark plugs...sorry

 

Thank yall for using Rockauto.com

 

Just a shot in the dark for you here and I may be way off base for your issue but: I had the same misfire code and it was my fuel injectors. #1, 7 to be exact. I replaced all of them. I also had the inital stall or rough idle at first then it either died or straightened itself out. The stall was from fuel overload when the injectors leaked down and then loss of fuel pressure. The truck sat for 18 mos. in a storage building with gas in it. Gummed the injectors all up with that lovely ethanol.

 

That site is a life saver,lol. Just a few purchases for my Dodge but my wifes CRV is built from rockauto.com

 

Just keep them in bussiness lol and they will hopefully keep their prices down
