There are many vacuum lines and hoses under the intake manifold, and it is not that easy to remove and reinstall.
The rear anti-nock sensor is on the drivers side as the link shows.
A pair of hemostats, a good light, and an extra pair of hands is helpful.
If you remove the alternator you can reach the IRIS check valve and hoses.

Sorry Svx... wats a hemostat? And where is the 'rear' knock sensor? The code I get is for LH knock sensor.. also some people suggest replacing them in pairs, additionally. how long do u think it would take me to get the intake off?
Thanks for the links and help guys....
