So I'm fighting the p0171 cel I've replaced the front 02 sensor with new denso unit, replaced spark plugs and wires checked for vac leaks, cleaned maf twice with maf cleaner, cleaned iacv valve, cleaned throttle body, ran fuel inj cleaner through gas tank, swapped a used junkyard maf. And I still have this p0171 code hahahha truck drives fine just want to fix the issue.
My 4runner is a 1996 with the expensive Maf sensor so instead of dropping 350+ for a new one id rather pay 100-150 for a 99+ mafs if it can be made to work. Thanks
