I have included a picture of the part I'm tring to figure out what it is?? Drivers side, under the fuel rail by the middle injector, there is a black plug that looks to go between the intake and the head. Is this the Knock sensor??

The picture was taken from the passanger side looking at the drivers side.


Thanks for the help

 

Yep..

 

that looks like a real joy to change!!

 

oh yeah... a lot more of that top end is coming off for sure.. could just be the wire, but even so you will have to take off that lower intake
