2002 Lq4 knock sensors?
I pick up a 2002 LQ4 complete harness and all to put into my malibu. It has 49520 miles on it from a totaled truck. ( I know lucky find for $850
) I started taking it apart to start my inspection and freshen up. Got down to the knock sensors and front came out and looked brand new. The back sensor is so rusted I cannot get it out. I litterally pulled the nut part of the sensor right off
. WTF how am I supposed to get this off so I can get the valley pan off???? Any help would be greatly appreciated.
