How's a going everyone, I'm new here and made an account so I could potentially get help for an issue with my truck. She's an 03 FX4 Off-Road w Auto trans that's got 222k miles on the clock (bought her at 151k) and for a while now I've been dealing with various trouble codes on the motor. Originally lean codes for both banks which after fixing them are now rich codes for both banks. Overall the engine/fuel parts that I've replaced so far over my 5 years of owning her have been the maf(2018 & 2021), 02 sensors (November 2021), pcv valve (October 2021), intake gaskets (February 2022), the notorious pcv elbow (November 2021), thermostat housing (2021) and fuel filter (2018). As far as I know I believe the plugs/wires are original and she idles in the 700rpm range like normal. Also every now and then when at a stop and shifting from drive to neutral or reverse the rpms drop to around 500 and lights flicker like she's gonna stall out before returning to normal. Anyone have any ideas by chance?
