Drove my X to lunch today and happened to be crusing along with the stereo off, since I had gotten a cell phone call earlier. I noticed a fair amount of detonation on moderate acceleration. This is with a 5-speed, 2000 V-6.

Since I haven't been home from work yet to look through the service manual, can someone enlighten me on whether the timing is adjustable or not? I'll probably find out when I get home before I read this, but I'd solicit any other opinions on the matter anyway.

My wife filled the X up with gas the last two times, so the quality of the fuel is unknown at this point, too. I'll ask when I get home. Not sure that the detonation hasn't been there for the past two weeks (since I bought the X) or not.
