Need HELP ! 1999 Honda Civic D16y8 rough idle up and down

I’ve replaced a lot of parts . Bought this 99 civic EX with rough idle problems . Did oil & oil filter change,coolant change,IACV replaced , TPS replaced , MAFS replaced , fuel injector and seals replaced,fuel regulator replaced, fuel filter changed, had it timed & distributor adjusted and with all that . I’m still having the same issues .

Codes? Did you buy OEM or aftermarket sensors?

That will be your problem. Sensors need to be OEM Honda or direct from Denso. I’ve never heard of WVE
