EGR Valve?

So, I have taken out my EGR valve to clean it becouse Im having some issues with it. I get a P0404. I cleaned it with carb and intake cleaner. Do I need to lube it up with something becouse it seems to stick a little when I let it close. I wouldn't think so becouse that would make the soot stick to it. Any ideas besides replacing it...lol Also, people have told me that leaving it unplugges can mess with the fan and VGT. I notice that my truck runes better with it unplugged and my fan isnt electric. Are any of the f350's electric?

Matt at Gearhead told me that having it unplugged will make it so the fan will only operate at 33% of the speed that it is supposed to. I am pretty sure the F350's have the same fan as the F250's and yes they are electric (the clutch is). They just look like the old school belt driven fans.

I have also been running with mine unplugged and can't tell the difference but I have only had mine unplugged for about a month. It's not exactly 100 deg this time of year either. Lol. If I notice anything this summer I am going to plug it back in and lay it in the valley til winter. Matt told me that doing that would work just fine as long as it has a circuit threw it.

I have seen that too. I don't feel like paying 200something bucks replacing something I didn't want In there in the first place.

So unplugging i can drive my truck fine? Mine is messing up the valves in the egr are getting stuck open and making my truck run rough. Unplugging it I hope will work to give me time to save money up to delete it.

Yea I'm in the same boat. When I took mine out I threw it away. That was before I knew about this. Ima go to a junkyard and see if I can find one to have for the summer in case I need it.

So far all I have read, to incude your links, is a bunch of someone said someone said stuff. My VGT and temps even while towing all act the same as before when my EGR was plugged in and working fine. VGT cycles and temps stay normal. All this while my egr valve is unplugged.
