So I am having issues with a misfiring a couple of weeks ago I hauled a dump to the landfill and after doing so I noticed my car having issues staying alive so I turned it off and on and went back to normal but as soon as I put load on it and come to a stop starts acting weird and throwing bank 1 lean condition so I replaced sparks plugs about 20- 30 thousand miles ago change the file filter two months ago and a couple of weeks ago did the fuel injectors and hadn't had a check engine light besides the p0496 but that happened after I changed fuel injectors but now I'm only getting a bank one lean condition after driving for about thirty minutes and is doing the same thing again
"lean" means too much air. Nothing to do with spark plugs.
p0496 means unexpected evap air flow (you can look these up yourself on obd-codes.com)
to me it sounds like you have vacuum leak in the evap system which is letting unmetered air into the engine and causing the mixture to be lean.
you can search Scotty's youtube channel for the videos he made about fixing evap leaks.
