Dont Idle Right
I have a 95 corvette, I put a 52mm BBk throttle body on and a Granetelli mass air on my vette, and now the idle is above 1k rpm and it dont seem to idle right, it just fluctuates low then high like 1300 rpm I dont know what to do...If anybody knows how to fix it could you help out in explaining my problem

I had the same problem when I chnged over to the BBK 52 MM.
Check your throttle cable and make sure it has enough slack at idle to return the linkage at the throttle body back to the stop screw.
If your idle is high you and you can pull back on the throttle body linkage and it returns to normal you need to add slack.
Follow your throttle cable back aboiut a foot and you will see a small
rectangle witha push button on it. When you press the button it will allow you to adust the cable.

Yes. But make sure it's the cable from the throttle body. When you depress the button it will allow for minor adjustments. You want the throttle body to close all the way with no pressure on the pedal. It should go all the way to the stop screw. You also want the throttle to open all the way with the pedal to the floor. So with the engine off have someone press the pedal to the floor and manually check it at the throttle body.Also consider checking the output on the throttle position sensor after you have adjusted the cable. Hope this helps.

I pressed The the button I took the throttle cable off the Throttle body Pressed the button It didnt seem to adjust easy the button is hard to push...Another thing when I did this and put the throttle cable back on the throttle body when the throttle sits back to the screw is there supose to be any slack in the cable? I have slack... Its like the cable still needs to be set back about 2000 of a gap for it to sit n the screw and idle properly I have to keep pushing the throttle back then it idles great, but when I rev up sometimes it sticks at that tiny gap which causes it to idle at 1000 or above
