OK,So after replacing my passenger side valve cover gasket on my 98 4runner limited 4x4,I now get a po325 code,Which is a no.1 bank circiut mallfunction knock sensor.I know this does not mean the knock sensor itself,But the wiring instead.I had to move around some wires and disconnect a couple plugs right behind the timing cover and I think this may be my problem.I'm going to try unplugging them,give them a cleaning and re-plug them.Has anyone had this problem?Thanks!

 

BTW,The truck runs perfect and no leaks!I cleared the light out,And hasn't come back on yet,Although I haven't gotten back on the highway yet up to speed.
