So I just finished doing a swap on my 7. I took all tha emmisions junk and egr valve. I made block off plates for everything I removed but now that I turned tha engine on sounds good no fluid leaks but its idleling at 3000 rpms.

I loosened tha throttle cable and tuned tha idle screw in thinking it was tha problem but still tha same thing idleling high.

So I checked all tha vacuume hoses to see if I missed 1 but I can't seem to find any so that means I connected all of them. Do any1 have any idea why is idleling so high.



Please hit me up.

 

if you have a bad quality gasket on the lower intake manifold it may have broken from the pressure on start up and that can cause high idle. Happend to my girl friends FD.

 

damn bro i didnt think of that till u told me so i checked it out n yes! when i took it apart i took a big chunk of gasket with it...thanx man u safed my life!!!!
