Hey guys,

Haven't solved this problem yet, soo...

I have this severe throttle delay (~2 sec) only when the truck is warmed up and only after coming off of a stop. In the morning or right after i just start the truck after sitting for a little bit, the truck runs strong and there is immediate response.

I also noticed that this is accompanied by a rough idle at the same time. If i am stopped at a light and let my foot off of the brake and roll, I feel like I am rolling on some extreme mud tires.

Neither of these problems occur all of the time.

Any ideas?
