Im having a problem with it right now. When the car is cold it runs fine, i runs normal, no problems. But when it warms up it idles a little rough, and when under load it feels like it is missing. like it dropped a cylinder. i have no clue what is causing this. Anyone have any idea as to what it is? any help would be greatly appreciated  :help2:</p></blockquote><p></p>
