PO441 is the error code for the evaporative emission control system. This system is fairly complex and there are a few things that can go wrong with it. Maybe a visit toa Chrysler service agent is your best option, its hard to tell whether this is related to the knocking noise but i would be checking engine oil level on the dipstick for peace of mind. A roadside worthiness check will deem vehicle unroadworthy with this code apparent. I would definately have the knock checked out it could be minor or, it could be something that will leave you on the side of the road. I hope it's minor so you can keep on motoring.

You wouldn't think a gas cap would be that important, but it is. When it's loose or cracked, fuel vapors leak out and can throw the whole fuel system off. This causes a reduction in gas mileage and increases emissions. What causes it: If you get an error pointing to the gas cap it means fuel vapors are leaking out of your cap. This means the cap is either cracked or just wasn't tightened well enough. What you should do: If your car isn't feeling jerky or strange when the check engine light comes on the first you should check is the gas cap. Pull over, retighten it, and take a look at the cap to see if it has any cracks in it. Continue driving and see if the check engine light turns off. Alternately, you can purchase a gas cap for about $3 at an auto parts store. All you need to do is take the old one off and screw on the new one. If you've already made it to the store, you might as well just replace it. While not car-threatening, it's good to take care of this right away to improve gas mileage.

Not a fuse washer relay.

If the light comes on at times there will be a code stored. Go get codes read before you spend money on other repairs. I dont know how the engine got gunked up with 50k miles on it and with todays cleaners in oils and fuels so im going to call BS on what the dealer told you. How does he know?, did he pull valve cover, intake,or use a scope to look into the engine?

Chrysler 3 5 FIRING CYLINDER ORDER here you go

a whining noise sounds like a power steering pump going shut

could be carbon buildup or a bad EGR valve. Did you disconnect the battery to let the computer learn the new part? However that doesn't rule out these an open or short in the 5 Volt reference circuit Open or short in the ground circuit Open or short circuit in the PCM controlled voltage circuit or a bad pcm or you got a defective egr valve

The sw is on the stalk to left of steering wheel.

run the fault codes and check for an EVAP venting problem as that affects the refueling process and engine problems after refilling

I would suspect the fuel pump is the problem, it may be sticking at times and this causes a no start. The pump is located inside the fuel tank and it is electric.

yes it's either broken or plugged with the skylight retracted look for the drain hose if not look toward the rear of the opening there is probably two drain hoses
