Engine Mechanical problem
2002 Hyundai Elantra 4 cyl Front Wheel Drive Automatic 110000 miles
----------------------------------------------------------------
I got a p0441 code incorrect purge flow and I changed the gas gas vapor canister vent valve, I m guessing that the vapor canister itself, I tested the purge valve in the front and it's still getting current. but after driving it for a while the damn thing still pops up, I was wondering if anybody knew what else could be causeing that code.

ps- I put a resistor on the IAT sensor soo it shoots extra fuel, and theres a hissing noise coming from the gas tank.

thanks,

Your evap canister lives rt behind your fuel tank w/3 lines running from it. you need to examine evap canister and the lines back there sounds like you have a leak in the unit itself or the line. hopes this helps
