I have a 1996 Buick Century 3.1L V6 that only stalls when it rains or it is wet outside. Once the engine heats up it runs perfectly fine, but it takes about 15-20 minutes to get running smooth. I am not sure what this could be. My check engine light came on and it says a code P1441 -EVAP System- no flow during purge cycle. I thought this might be the egr valvce gasket and replaced that, however the problem is still there. I need some idea of what it could be. Thank you
I would check the Mass Air flow sensor or crank shaft sensor. I would start with the Mass Air Flow first. Because it actually has the outside air running across it. You can buy a mass air sensor cleaning kit but you have take apart the air flow vent to get to it to clean it. And sometimes it don't help you have to just replace it. Its not a major repair.And not that hard to do. Call around for best price. Any little shop can do this. ...About the crankshaft sensor I've seen them go bad but ussally the car want start at all. So check 2nd...Hope this helps
EGR and EVAP systems are tow different operations
fixing what you did doesn't fix the code revealed

P1441, EVAP Emissions System Flow During Non-Purge.
you seem to have an evap problem these problems are hard to diagnose sometimes it can only be the gas cap or maybe rust around the seat of the gaz cap
get the code erase and see if it comes back on and if it does check gas cap and arroung the filling neck if there is rust if no visible rust apears you will have to get it check with smoke to see where it leaks
hope it will help you
Have a great day

SOURCE: 96 Buick Century won't pass imisions code P1441
code is evap system flow during non-purge
check the hoses for holes or broken disconnected hoses also check the fuel cap emissions diagram under the hood will give u the location of the evep purge solenoid if all checks ok then replace the soienoid and clear the codes
rank & vote my solution

If your car runs bad with an EGR code then I would suggest that the EGR valve be replaced. I would like to know what code was set on your computer. It would help greatly. When the EGR malfunctions, you will have rough idle and possible stalling. If you have a code indicating EGR it may also condem the cat converter.Please show any codes that are set. Thanks Moe

it has a digatal egr valve remove the egr valve and lean it with top engine cleaner from GM, with a tooth brush, then test the stepper motor with an ohm meter if it mesures more than 6 ohms replace it.

I work at autozone and as the man said the evap system maybe the fault that can up on the obd 2 code reader but if no ither codes came up then you
can have a problem that is not code related ( as early car 96 to 2000 the service light only covers things that are in the pollution part of the engine..
the newer cars the service engine / malfunction light will come on for many other things
if your egr is not seating on idle then you would stall at a stop if you egr stays closed then your car would be polluting and could not pass e-check
if the car is not running properly and it has a multiport fuel injected system /coilpack system
change the cranksensor ..If you have a distributor
change the pickup coil/ ignition control module
these are both in the distributor...
as long as you have good wires & plugs you should be in good shape
