My 99 318 durango when it starts is idling iradically when i start it up and let it sit for a while i didnt do it until after i put my cold air intake on it so i think it could be a vacuum line or something but i am still not sure so thats why i am posting this, so if anyone can help me i would much appreciate it.

 

Have you try taking the cold airintake off and pull the air cleaner box back on, then see if you have the same problem.

 

Sounds like a full tune up is in order first.

What spark plugs are you using?

The other problem could be the Air Charge Temp Sensor, or cleaning of the TB.

 

I put a tune up kit on it already and I have cleaned my throttle body but could there be a leak in the intake because i pressure washed my engine one time and it would do the same thing. It also could be from high milage because i have almost 155,000 on it though. I might try putting the stock airbox back on it and see what happens. Also when the code the check engine throughs is for the pcv valve which i had changed also when it first popped up so if the airbox doesnt fix it i dont know what the hell I'm gonna do.
