Can anyone help me with this code?
Thanks!

 

P0441
Generic
Evaporative Emission System Incorrect Purge Flow

Check your gas cap, Then check your vacuum lines.

 

So since getting the P0441 code around March of this year. Replaced purge valve with new (Bosch). Cleaned maf and IACV. Also had my mechanic change all plugs, wires, and both coil packs. The code has recently come back and he’s doing a smoke test on it tomorrow. Could the P0441 be causing the rougher idle? I will say it’s worse after driving a couple miles and sitting in gear at a red light. Anybody have any idea what else could be causing the rough idle???
