I just installed a new 75mm throttle body on my 2000 5.4 and now I need some more slack on the throttle cable. Right now it revs up to 1900 rpm at idle due to the needed slack. How do I get more slack out of the cable?? I can only find forums on how to reduce slack. I used to have a throttle body spacer but removed it, as well as the throttle extentions. So now everything is back to stock.....any solutions????

 

Your local Ford dealer ought to be able to order a longer cable that's compatible. Aftermarket companies have them as well.
