detonation I need help. I have some really bad pinging @ full throttle when I hit about 5000 rpm`s.I have heard dozens of remedies.Who has successfully fixed this problem? Has anybody tried the pcv mod to keep oil out of the throttle body? I don`t understand how small amounts of oil could cause detonation. Any and all advice would be greatly appreciated. I have `02 Z with A4,2:73,K&N FIPK,& SLP Y-pipe.

Ruled out the bad gas theory... unless every gas station has bad gas around here! <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
Also have installed 160* thermo and used the water weter with about a 30%coolant 70%water mix. Helped a little (I think), but still getting some pinging.
Still waiting on the fan swith!... That seems to be on perpetual back order <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" />
If all else fails, I will definatly be doing the pcv mod or inline filters... or whatever it takes <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
