I have a cali-spec 99 i30. So I found a tutorial with much less detail and pictures and headed out to chance my KS.
The KS was hidden behind a crap load of cali crap added to the car. Took me 5 hours.
I had to make custom hooks and holders out of hangers and a swivel head saved me. A socket extender with a swivel had difficulty fitting much less a hand. To remove it I got the socket there and used a clothes hanger to align the socket on the bolt and removed. Getting it back was the problem. I put the screw in the new KS and plugged it in then used hangers.
only on fed spec.

There are members here that swear they can change a KS on a Cali-spec Max in 10-15 minutes. I'm still waiting for the youtube video that I've requested on multiple occassions...
Well, just the things that don't have tutorials already

-A painting guide (For the newbies to painting, like always use primer before painting a new color, how to avoid paint bubbling, what to use to sand old paint effectively, and ect. But I learned all this through trial and error... but mostly error and so it would probably help people who had never touched a can of spray paint like me. Most of the guides I read assumed I knew the basics and such which I didn't haha) P.S. Sandpaper SUCKS at sanding paint, the little rocks in it all rubbed off before I even finished an area I ended up using those things for belt sanders with grooves machined into the belts)
-A guide to pulling out various parts inside the car like the dash, center vents, various vents, removing the roof lining.
-Removing the beeper in the car
-Installing various motion sensing alarms
-Replacing E-Brake cable
-Fixing dents with regular everyday tools (Maybe?)
-Cleaning the IACV valve (Not sure if I had that right, but I couldn't find a guide for it, but I'll make sure to search again to double check)
Thats all I can think of off the top of my head, I remembered searching for these things and finding info that was hard to understand because of the complexity in which it was written or were not covered.
Haha I'll be sure to make notes from now on whenever there is something that there should be a detailed guide for, but is not there.

#2. Do you hear engine knocking? Have you try with premium gas. Premium gas should help even the KS is shot.
#3. Poissible
#4. Engine knocking, poor mileage.
Boy, wish pmohr was around.

Today was the day I grew a pair of (you know) and decided to change the knock sensor. I have read all your comments and tips, but I still couldn't do it. So the problem is my wide palm does not fit where the knock sensor is located. So I've had my wifes little hand get in there (after much convincing), but did not have the strength to loosen it. Anyway after 40 minutes many cuts, and b!tching from the wife I am still stuck with a bad knock sensor. If anyone is NYC or LI I could drive to, there is a whole 60 and a case of beer ....... PLEASE HELP

Good advice...
Even-though I didn't use a 12 wrench and it didn't take a half-hour I finally got it done. I had to use a socket wrench with a 12 on there and use a regular wrench on the end of the socket wrench to break the bolt free. I thought when I broke it free that was the end of my troubles. How wrong was I. Jamming my hand in that little cave of a hole where the Knock Sensor is located and then trying to loosen and tighten that at bolt was a killer. Until i saw this post I was convinced that the only way was to take the intake manifold out for it.
After doing this I did take a test drive to check if everything was working fine. Should I have noticed anything different if my old knock sensor was bad? When i was driving, I noticed a little more power from the lows and my kick-downs when I stepped on the gas were quicker. But other than that this was some pretty good info and a great way to save some green.

Great writeup, I'm going to try this....but have a Q.
Last week, I was experiencing a rough idle, nothing major but a noticeable hiccup. I decided to change the spark plugs. When I pulled out the #4 ignition coil it basically ripped off of it's shaft. I found my problem. I replaced the ignition coil, reluctantly with a part from Autozone (I replaced all 6 with Hanshins back in 04). I did this on Saturday. Car ran smooth, no more rough idle, power seemed good.
Monday, rolls around and my wife takes the Max out and tells me the CEL came on. I ask her if anything had happened. She tells me she accelerated very quickly after hitting the overdrive button and then the light came on. She also complained that it still has lost power. I took the Max to Autozone to get the codes checked and I got P0304 (cylinder 4 misfire) & P0325 (knock sensor condition).
The car runs smoothly and I don't feel a misfire. Is it possible that the misfire code was from last week and since I didnt reset the ECM, it is still showing up?
Also do you think the KS code is piggy backing off of the misfire code. I'm going to take it for a spin tomorrow and see if I notice any loss in power. Will definitely use this writeup and change the KS to see if that solves the problem. Let me know what you guys think I should do.

I just ordered my an oem ks from ebay for $52.00 shipped. I have very little power above 3krpms with code 0325. With no misfires, sounds like you should really look at the #4 cyl, could be a bad plug, it's already bad driving with a bad ks, I cant imagine a faulty #4 cyl.

Knock Sensor - Hard to Reach
Just did mine yesterday. I was able to get the old one off with the techniques above, but there was no way to get my hand in to start screwing the bolt back in. I tried jamming my hand in there, but a wrist laceration would have cost me more at the emergency room than I stood to save on this one.
Solution, I loosened the connector block that sits right in front of the access area. There is a 10mm nut on the underside of the connector block. I loosened it until I could tilt the connector about 1/2 inch. Then I could cram my hand in fairly easily and start the bolt. I will post pictures.

This past sun my car went thru a little puddle of water. After that my been driving weird and cel came on. I have two codes P0100 which is Maf malfunction and P0325 for Knock sensor malfunction. My car can't rev pass 2500rpm and stall at times while idling. Do u guys think this is more of a Maf issue then knock sensor?

The Wiz is right, a common maf sensor problem is no revs past 250 rpm, its easier to change out, try getting a used one and im 100% is your maf sensor

Guys I let my car sit for a week and haven't drove it since last sun. Well today I went to check my codes and now the Maf code went away. Also my car can now rev pass 2500rpm. However, even though cel is not on there is still a P0325 knock sensor code. Car drove fine today so have anybody have this issue before?

Yes, that's how it's designed. The KS code will never light the CEL.

If you're getting the KS code then there's obviously a problem somewhere.Have you tested the KS, the subharness, or the main harness?
