ok so sometimes when my engine is at idle i will run rough...its not a dead miss, i think, and the guys i work with think its the EGR. i have no codes. but if its at idle, then that means the EGR isnt closed all the way. so has anyone ever had this problem to where the pintel wouldnt shut all the way to completely close off the flow of exhaust gas?...in other words, its dirty?

 

What is the age of the plugs, wires and other ignition components?

 

i just replaced all the plugs and wires...they were the org. wires lol. and as far as i know its the org. coil.

it doesnt do it all the time. only at idle. like ill shut the eng off. then go into the store for like 10-15 mins. come out and start it, and it will do it. but ill drive like a mile and come to a stop and it doesnt do it.

 

Cap and rotor?
