Hi Guys, I got this P0441 code on my 2005 Murano. I have replaced the purge flow sensor three times OEM, Doorman, and generic, and the check engine light is still on. I recently replaced all catalytic converters, which I bought from amazon and they are the Evan Fisher brand. I am not very confident about their quality because I still get a burning oil smell from exhaust. My mechanic who is a friend also checks the exhaust pipes for the leak with the simple water spray test and he said there is no leak. I have replaced the fuel cap also. I don't get any other codes with my Autel OBD handheld and my buddy has a really expensive code reader and didn't get any other code with that either. I am tired of burning money for this car. Please help.
