My check engine light is on. Code 0441. Evaporative Emission Control System Incorrect Purge Flow. Truck runs fine. Sometimes the light goes out in a few days, sometimes it stays on for months. Any suggestions on how to fix this? 2003 Hemi. Only mod is a K&N CAI.

 

i used to get this code once every few weeks, i cleaned my tb, made a cai, and ran some lucas injector cleaner for a couple tanks and i havent seen it for months. mine would never turn off by itself, i always cleared it by disconnecting the battery

 

I'll give the injector cleaner a try. I'd clean my tb, if I know what a tb was. tb anyone? tb?

 

TB = Throttle Body
