Check codes P0133 stated: #3 misfire & P0130 slow response O2sensor bank 1, sensor1.
I had spare Coils & wires from a 40K exchange engine from japan, installed @ 135k. (Rod failure x excess RPM)
so I pulled the plugs and changed them to new Bosch plat.4s. NOTE when I pulled #3 coil to pull the plug, the connector tip was burned and split. The plugs were new 5k ago (with eng. change) but the DENSO K16TR11 plug seal failed between the insulator and the hex body, the ceramic would move a 1/16" causing hot gases to leak burn up the tip of the coil on plug connector.
I changed all plugs, wires and coils: reset codes: runs good now.. will the code 130 come back?
?? Did this missfire condition cause the code P0130?
Did it damage the O2 sensor so that it forces me to change the O2 sensor or will it be ok.? or is it just better to change it, as it has some miles on it?
THANKS FOR ANY INFO...BEMER
