06 4.7 standard output just changed the plugs at 30k an it still stalls at a red light or when im stopped holding the brake,i also heard it could be the pcv valve doin this,is that correct.what else could it be

 

Is it throwing any codes?

 

no,ive read a few thread about it, each thread has a different solution.plugs,pcv,fuel treatment,an so on.could the pcv valve cause this

 

we dont have a pcv. it is called a egr valve. if the valve is stuck it will cause truck to run terrible. your problem is the throttle positioning sensor. 109.00 at your local dodge dealer. it is the sensor that is on your throttle body. has two torx screws holding it in. it is going bad. once you replace it. you may have some erractic idle. just loosen up the screws a little while truck is running and turn sensor clockwise as far as it goes. this is the factory setting and truck should be fine after that.
