P0441 Evaporative Emission Control System Incorrect Purge Flow


there you go !!!!!

My CEL has been off and on for 2 years, but in the last 3 months it started staying on consistently. Checking codes w/ manual method and scantool, it is P0441, and the diagnostics on the scantool show a pretty awful fuel trim. Along with this, my fuel economy has gone in the toilet, from 22-ish around town to 16-ish.

No changes in driving to explain it, so my feeling is that based on some research online, the evap canister is shot (seems odd for 88K miles though...). I have also read though that this code can mean a leak somewhere in the evap system, and needs to be diagnosed with a smoke test. Don't really want to take my car to the stealership without having more info. So, anyone have experience with this on a 300M (or another LH series car with a 3.5 HO V6)?

Thanks!

Yeah, getcha some O2 sensors and a new gas cap. I'd be willing to bet all your problems go away after that.
