Default Throttle body question.

Where do I drill the hole in the throttle body plate to make my H/C Z06 idle better? What size? :confused:

In my opinion, you don't. That is an old carb trick. The purpose of the hole in the throttle plate was to allow the throttle blade to be closed far enough at idle so as not to expose too much of the the fuel transition slot in the carb main body. That is not an issue with fuel injection. Your idle speed should be set with the throttle stop screw and the IAC. An otherwise large amount of throttle opening won't have the negitive consequences with a throttle body as it would have with a carburator. Good luck.

Nowhere!Dont drill anything @ your z06. If you have problems with idle and your engine is stock ---> see your dealer .If you have anykind of perfromace mods <--- take few steps back and see if something has isntalled wrong etc or consult with the shop who has done it. Your car is way too high tech to have something from stoneage like idle problems :smash:
