Improve MPG on 7.3 Powerstroke

what is up guys welcome back to the channel today it is an absolutely gorgeous day out and so I decided I should take the opportunity to get a little work done that I've been telling myself I need to get done for quite a while tomorrow all my current subscribers thanks for tuning in again anybody that new I encourage you to subscribe so you don't miss out but today we are going to be or I'm going to be trying to increase the fuel mileage on my 7/3 a little bit by cleaning out the exhaust back pressure tube that's something I've been telling myself I need to be I need to do for quite a while I haven't done it on this truck and I would be willing to bet the previous owner had no idea about it so I'm sure it's probably pretty dirty in there before I unplugged my exhaust pressure valve it started to malfunction on me open and closed when it shouldn't so I have a pretty good idea that either the sensors bad or the tube is pretty clogged up I guess we'll find out but I'm gonna go through clean that out everywhere I've said or everywhere I've looked has said that pretty much if that gets all dirty and clogged up your chances of having your fuel economy drop a little bit I'm pretty good I'm not getting that bad a fuel mileage but I think it could be a little better so we're gonna see if this helps out I don't know if I'll make this a complete how-to video I might either way I want to show you guys what I'm doing alright so for those of you that don't know on these 7.3 power strokes you have a tube that runs from your passenger side exhaust header up to the very front of the engine to where the sensor connects I've seen a lot of people come in from underneath me being in a wheelchair exactly ideal for me to crawl under the truck so I'll show you how I think I'm going to be getting to it through the passenger side wheel well not sure if you guys should be able to see it but right in there you can see the tube it's a little wet already but you can see the tube coming off the front of the header and that's a 5/8 nut that screws on or holds it in place so I should be able to get to it right from there through the wheel well and unscrew it up there or down here and then I'll show you up top where it is alright so up here on top of the engine you'll probably notice that my engine looks a little bit different in this area that's because I deleted the fuel bowl and have a full kind of custom fuel system built for the truck if you're interested in that video it's on the channel but what we're looking at right here you got your high pressure oil pump reservoir and then now here you're gonna have a little sensor down here you're gonna have a sensor that plugs in right there and that I already have it unplugged but that is your high pressure I mean your exhaust back pressure sensor so that's a one inch nut that you can use to get off not sure how well you'll be able to see it but underneath that knot it's kind of on to a bracket that bracket has a 9/16 nut holding the bracket in place and then right here is a 5/8 not just like down below and that's the other end of the exhaust back pressure tube so I'm gonna be working to get those undone and I'll update you in a little bit all right so here we go we got it out and as I suspected well first of all so it kind of sits in the truck just like this this attaches to the bottom of the sensor that attaches to the front of the manifold this one I got out through that hole like I had hoped for wasn't terrible it was just coming out about an eighth turn at a time which isn't always fun but it got it out this one isn't terrible either you have to work around the fan if you have a full-size wrench I don't have any snubby wrenches that would have made both of these a lot easier but it is what it is I got it out with full-size wrenches I'm not sure if you guys will be able to see this at all but it is absolutely [Music] Cape in there kind of as I expected yeah I'm not sure if you guys will be able to see that or not but it's absolutely just I mean I can barely even see into it I'm surprised I'd be surprised if anything was flowing through it at all so I think I'm gonna try to get that sensor off I don't have a deep 1 inch socket it's going to be a really tight squeeze to get a 1 inch wrench in there but we'll see what we can do yeah I'll update you guys as I'm cleaning this out and show you how I do it alright guys well we got it all cleaned out how I did it and how I've seen other people do it is to get a drill and I use some weed whacker Xtreme I've seen people do it with speedometer cable I'd be a little careful with that because it's metal but basically you thread it into the tube and which is not easy thread it into the tube and spin it and use I use wd-40 and brake cleaner to help break up all the soot and as you can see it was disgusting it took a long time for me to just be able to break through all of it to be able to get the cable in but I think I got it all cleaned out I don't have the right tool to get that sensor out right now I don't have the socket and none of my wrenches are gonna work so I'll get to that at some point I've had it out before and cleaned it out a little bit just the sensor part itself so I think that should be okay yeah I'm gonna start putting it all back together and getting it in the truck all right hopefully you can hear me and there's a lawnmower going on right now but we got get back in secured up here got the sensor plug back in there little tip lined up at the bottom first and get it started threaded down there and then finish it up up here it's starting to rain right now so I think I'm going to try to hurry through this and I will catch you guys when I'm done all right guys we got it all buttoned up down here don't know if you'll be able to see it so that right there that's what we've been working on oh if you could see it before I'll find out when I edit this but that nut right there got that fastened back down and we're good to go so now that it's all buttoned up I'm going to take it for a drive I don't expect to have any or notice any real difference doing this more maintenance wise and to hopefully improve mileage in the long run I have no idea if the sensors still good on it I don't know how much they are I don't thank you very much I might just go through and buy a new sensor and put that in at some point soon but nonetheless it's all buttoned up let's go for a drive all right first start up yeah she does like I said I don't expect to notice any difference with this but it's never a bad habit to take it for a drive after you start working on things as it should one thing I have knows that I don't know if it's just because it's warmer but I was having a fluctuation with my idol like it was trying to figure out whether it be the warm up or not or going to high idle mode I thought it was tuning right now I mean 71 degrees oil temp and idols holding the rock solid so I'll keep an eye on that see if this fixes the idol fluctuation I checked the CPS and there's no oil ICP check the ICP and there's no oil on that sensor so we'll see so we got the truck warming up that's why it's a little noisy obviously you still have the fluctuation in idle I'm hasn't gone away I still think it's a tuning problem because when I switch out of that - and I haven't seem to notice it at all we'll see keep an eye on it we're gonna check for codes now alright po4 75 should be the exhaust back pressure control valve which I know because I unplug the valve two three two he'll pop secondary circuit hi I've gotten that code before not a hundred percent sure what the cause of it is I usually get it after a really hard run and from what I've seen I think it's the feel pumped where it's sensing that the fuel pumps not keeping up but I have an air dog I'm not using the factory fuel pump anymore if you guys have any input on that one i'd love to hear it but for the most part I don't think there's any problems we're gonna clear those codes see what they come back and now we're gonna go for a drive see how it does oh the windows three guys well that was a dump now I'm in a wheelchair and I dragged controls so this thing right here is my gas and break our fuel and break fuel and break I have a video on that explaining that that's right now I don't really feel any difference it all seems fine there seems the same which is what I expected but now I have my feel pressure set 55 psi of 56 psi I think I'm gonna bump that up a little bit most people say - they try to run it over 60 I think is a little excessive but I think I could probably use one bumping it up to here I don't think I'm noticing any ill effects from having it there but sometimes I'll see a drop down to 52 or 53 or hi 50 twos or threes and having it drop down I think I'd rather have it drop down to around 55 instead of down to low fifties but overall truck seems to be doing fine get on it a little more here not college all seems perfectly normal I don't think we're picking up any codes all right I'll catch you guys back to the house all right back in the house truck seems exactly had it always has pretty normal we'll scan the codes one more time this is my edge CTS I just did a video on it as interested Stanford codes no codes were good so I think we're good I know this probably wasn't a very exciting video but it is one of those things I'll keep you guys updated on if I tend to see or if I think I start seeing better mileage off of this like I said most people most people say they do and that back pressure tube was completely clogged like I don't think anything was going through it so I'm glad I went through and did it wasn't a terrible job took me a few hours if I can do it from a wheelchair and hobble in my butt around I think you guys can get it done too if you're new here and you're not subscribed please subscribe don't miss out we got a lot of stuff already happening a lot of stuff that's in the works I'd love to share it with you guys all my current subscribers thanks leave a thumbs up and I'll catch you guys on the next video [Music] [Music] [Music]
