After a few days of pulling my hair out, I finally found a pretty easy way to do it.

At this point, anyone who hasn't changed it is probably due for sure. The reason you change it is because the backing of the knock sensor goes away and it becomes too sensitive.

New vs old.

Just for the record, that's my wifes hands, not mine

The knock sensor is located under the intake manifold behind a metal plate.

If you reach your arm in sort of by the cruise control box, between a few cables, you can reach in and get a ideal on how to reach it. You will want to practice finding it and training your arm to blindly find it. Once you get a good ideal how to reach it, you will want to remove the intake (for a stock car), upper IC hose, and the speedo cable from the transmission.

With all this removed, you can reach a full size 24mm wrench in, fit the open end on the knock sensor, and have enough torque to turn it.

The one thing we had bad luck with was undoing the original knock sensor from the car. It's held on by some sort of clip and we just cut it and left it. Other then that, it isn't that bad of a job after you figure out a few things. Finding the knock sensor is going to be the hardest part about this job. If you just can't find it, then jack up the car, and look up for it above the downpipe and look below the intake manifold with a good light source. You will have a better view and some suggested removing the exhaust (downpipe) to remove it, but even tho you have a MUCH better view, I felt the knock sensor was even farther away and out of reach with the car jacked up, and it would still be hard to turn, but it is sort of easy to find from below.

Good luck

so here is some good news for everyone.

I purchased a GP Sorenson Knock sensor for a 1991 Mitsubishi Eclipse Gsx from Advanced Auto parts.

$58 it cost me and they got it the next day.

soo i pull my old knock sensor( which i baught from Mitsubishi directly $115 ) . i open the Gpsorenson box and find out that they are excactly the SAME knock sensor. The gpsorenson one says mitsubishi on it and same number, same wire colors .. same everything .. they are the identical knock sensor

soo anyone that ever needs to replace theyre knock sensor .. dont waste ur $$$ at satan . Go to advanced and order the $58 Gp Sorensen knock sensor .

I know it's a foreign idea for most of us here, but you might want to try taking the car off jackstands.
