wants to die
 

I have a 98 F150 xlt 4x4 supercab 4.6 ltr

Seems like it wants to die when I come to a stop I quickly give it some gas and its fine. what does this mean guys? whats the best spark plugs to use on my truck? I have a K&N filter in a stock intake,
hyperteck programmer,3" single exhaust all the way with a V-FORCE muff.
getting remote start and the bumper driving and tail lites will have the emergency strobes just like the police has

Sounds like you need to clean or replace the IAC valve. Might as well clean the throttle body while you are at it.
