i think all cars will rev high to warm up. but dying would be from something else. try cleaning your maf sensor and see if that changes anything

It all stems from when I put the svt factory intake on it idles high then will drop down and then idle way below and feels like it wants to die so I rev it up and it goes back to normal it does it when its cold and once in a while when i drive it

And I do have a sct xcal program that I installed o2 delete and egr delete
