Re: why does my car do this!! Damn it might be. I did drill it. but I used the specs from this site and installuniversity.com. Is anyone else having this problem. I know it's not a big thing but it is kinda annoying.
Re: why does my car do this!! I made the mistake of drilling my tb hole too big and mine had the exact same symptoms.. If you were coasting and you the clutch pushed in it would idle between 1200 and 1500 rpm.. Once you stopped it would go down to 950rpm.. I corrected the oversized hole and the problem went away and it never came back..

Re: why does my car do this!! Yeah, the TB hole is a little to large for just a cam. However, once you put heads on your car that 7/32 hole should be fine. On the otherhand, if you are unhappy with the idle characteristics at the present time then JB weld the hole and redrill it smaller <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" />
