I just swapped my stat with a new OEM. It was 17 this morning, block heater was plugged in on a timer (3hrs) and idled for 15 min before leaving. Heater was cooking my feet. Prior to that, it took 3 miles to heat up with constant EBPV and the associated power loss after same idle time. Now, I am of the opinion, if you can't achieve similar results, suspect your stat....without a grill cover. However, I do want to get one...
Go get yourself some diesel clean additve in the gray bottle. It cleans and lubricates the injectors, fuel pumps and the likes. If its cold I.e 30 and below go with the white bottle. It may take a few tanks but it should help. Since owning my 7.3 with 136,000 I started at only 9.5 and I am up to 12mph only after three fill ups. The first two had the white bottle and the last one I put in the gray. Hope this helps.
I just bought a Costco sized bottle of the gray bottle! Excited to try it. Thanks
An OBDII adapter and an app for a portable device (link in my signature) will be able to read the sensors in your truck, and depending on which software you get - you may be able to conduct some tests. One thing's for sure... your odometer is lying - at least a little. Those tires reflect less distance traveled than actual. If you have access to software that can link to the ABS system (like AutoEnginuity or FORScan), you can set the correct size for your tires.
Boost leaks, exhaust leaks, and EBP sensor are high on the suspect list - assuming you don't use the truck for a grocery getter in town in the winter.
Miles, not kilometers:
I just paid $150 for a shop to look at my truck. And they didn't have a clue!!! They didn't even check for boost or exhaust leaks. When they put on there scanner it only read old codes but the DTC's that my Edge chip is now reading are P1280, P0705, and R0603 power interruption on (KAPWR) circuit! Fml. I'll research what they mean later but I can't figure out how they didn't see what my edge saw. Lol
These kids today... I tell ya. Modern vehicles pretty much tell the "mechanic" what's ailing the vehicle - no troubleshooting needed. Our "fossils" speak vehicular Neanderthal "Me hurt here", then it is up to the "troubleshooter" to sort out why.
Get the OBDLink LX ($60) (if you never own a Chebby, MX for $100 if you do) - Buetooth for Android/Windows, WiFi to add Apple to the list. Download an OBDII app or two (about 5-10 bucks each), and don't forget to look at FORScan for all platforms. Log your data, and some of the guys here can tell you more about your truck from the logs than those voice-breaking "mechanics" can with the vehicle on the lift.
I've cleaned my EBPS tube, which was pretty clean. When j start it up in the am, the RPM will kick up to about 850 or so but I'm not really hearing the whooshing of the EBPV closing. I get the feeling that my sensor is bad but am not reading any codes... Is that posible?
I'm also reading the code R0603 (KAPWR) Interrupted circuit or something. Does that mean anything to anyone?
Adding one more beat to the drum here, you won't find anything with a code reader. There are only so many codes these trucks can throw, and extremely few of them would solve a fuel economy problem. To figure out what's happening, the "palm readers" (they look at lines on a graph from sensor logs) need to see things like Mass Fuel Desired, Injector Control Pressure, Boost, Exhaust Back Pressure, and a few other sensors. If you have a smart phone, tablet, laptop, or whatever other portable computing device - you are about $75 away from having your own OBDII gauge set with logging and alarm capability, complete with Ford factory tests available to troubleshoot the truck.
i would never run a grill cover. at 10 degrees my engine only takes 4-5 minutes to get to 190 degrees, and stays there even at 65 mph on the highway.
I've never had my engine warm up that fast. I need about 10 miles before I'm up to temp in the winter. 4-5 minutes getting off the side streets in my neighbourhood get it off the cold peg.
Thanks for all you input Tugly.
Would I buy one of those "Palm readers" at any auto parts store? And then download the app at the Google app store?
What one needs is an OBDII adapter and an app to listen to the truck and log data. The "palm readers" I was referring to are guys on the forum that read the data in the form of lines on a graph. There are a few of us that can look at the sensor logs and see issues - usually leading to more tests or some wrenching. You can find plenty of details on OBDII adapters and apps in the OBDII link in my signature.

Does the heat ever get hot enough for you to turn it down? Does your needle seem like it never gets all the way up to operating temp? If you answer yes to those, it may be worth the thermostat and gallon of concentrate coolant and Distilled Water to fix it. Mine was stuck open and couldn't hold temp.
Stat is under $30 bucks at RiffRaft and housing is around $25 (old ones' tend to be rusted/corroded.
280km. I've checked my tires and the brakes aren't sticking. I cleaned the EBPVS tube and sensor which had no soot at all. I then decided to buck up and buy a new EBPsensor. I've been thru 2 tanks using the grey bottle of diesel Kleen. And I normally drive fairly slow and rarely push it but lately I've been barely breaking 45kph. I have also noticed that my Temps are usually in th 150-160 zors so I've bought a new thermo stat and will instal this weekend. Next pay day I will buy an OBD 2 adapt
