Just installed some Autolite 3923 plugs (one heat range colder than OEM) and yanked the NGK plugs.
Three Marlboros and one beer later, the spark knock is still there in all its glory. ??? ??? ???
WTF right? ??? ??? ??? ???
I only have 29 more payments to go before I own it outright so I considered a trade but then thought for a bit.  Between this rig and my Dakota, I've been making car payments since Jan 2000.  And its getting old.  Really old. :-[
So I wil try to hang onto this gerbil and feed it hi test in an effort to keep the spark knock at bay.  Have yet to hear back from the dealer on my trevails.  I plan to call them this week with a reminder of "Hey remember me, the customer?"  See what they say.  I pretty much can guess the answer......run higher octane fuel!  Yea, right!
Hopefully it will last until paid off.  Then I can go from there. ÂÂ
Sigh..........and I'm otta beer now! :'(

Best of luck to ya.

Hey Hamster, I have a buddy that has been a service advisor with Suzuki for years, I will ask him on Monday about the knock. Hopefully I can get a solution for you.

Ok, you're probably not going to want to hear this, but me being the glass half full kind of guy I am I have this little bit of knowlage to offer. I use high test in my 2.0 and I get an average of 27 to 27.5, which is pretty good in my opinion, with the cost of gas these days (believe me I know I work part time in a gas station ;D)I've learned a few things, believe it or not, on average, it's only about a dollar more for you to fill up with the super stuff. Maybey this will cheer you up.........Or not...... ;) Hang in there

retard the timing. check what it is, go back 5-6 degrees and see how bad the knock is. Also, have a check at you knock sensor - I dont know where it is or what the specific test is, but that would be my next guess
-
Ya, start at 3* retard, and see if it gets better,
unless there is no dizy then I don't know what else
to tell you

can you adjust the timing on an engine with no distributor, cause i'm sure the vitara's don't have them.
-
This is a long shot and maybe even a dumb idea, but could it be a hot spot on one of the cylinders caused by a clog in the water jacket?
If so, your temp might be in spec, but a cylinder might be heating up enough to cause detonation.
If you think it's a possibility, maybe you could get your hands on a temp gun and shoot the block for signs of overheating.
Just a thought.

Yeah, you can. There is an electronic pickup that is located on the rear of the engine head and is driven off of the cam. It is where a distributor would be if it had one... There is a factory pen mark showing where it was timed at the factory.

Hamster,
 I really doubt you want to hear my actual opinion, but I'll put it out there for you.  There is a knock sensor and that really sounds like the cause of your problem.

Hampster,
If your truck runs and Idle's just drive it. When something breaks then take it to the dealer!

Before you give up, have you pulled the EGR valve? (2 bolts & a < $1 gasket.)
I know yours is a diff engine than my 1.6, but cleaning out the the EGR passages allowed me to run regular. (1st time since it had 20K miles.)
