newbie with check engine light issues

[jetrail]

Hi everyone I'm a complete noon to ram trucks but I have a 2004 ram with the 5.7 hemi , we bought it on Sunday and it was fine all day Sunday and Monday , well yesterday the yellow engine icon pops up , I have the codes read and there is 3 of them p0157 p0159 and p2099 , all pointed to bank 2 lower sensor , I replaced it and reset the code then the thing throws a p0430 code . The previous owner said it would need plugs done soon and to get copper plugs , I picked them up tonight but my concern is could plugs cause it to keep throwing codes ? All of them on the printout from autozone had the possibility of it being a misfire . Any help is greatly appreciated

Overly gapped plugs will throw codes and cause misfires. A friend of mine was driving a v7 for a while due to plugs he took out a cleaned but refused to replace lol. The plugs should take care of it.
