Regarding the above stalling post. After freeing up the evap purge control solenoid with wd40 i have not had one stalling instance at any point with my fusion. I have been averaging about 16,000 miles a year. Sometimes i will just squirt a little lube in the solenoid for good measure. P.S. Also did the battery age reset proceedure. Sorry no link. By using forscan and a obdII to usb adaptor i was able to change how old the computer thinks the battery is. I now have my mileage back and am averaging 42 on my commute that is about 75:25 city interstate:city residential. Also the time lag between pressing accelerator to actual launch is much quicker. Previously i would mash accelerator and wait...then take off. It was disconcerting when attempting to pull out in front of people...ha. GLTA I may repost some of this info elsewhere in the thread as both issues were almost a dealbreaker.

how much fuel is in the tank? I was having a similar issue with the ssn message intermittently after fueling or anytime while driving when the engine tried to start after being in ev mode. Finally after about a month it threw a code for the evaporative emissions controls. The evap control solenoid was allowing excess fuel vapor to poor into the throtle body and essentially "flooding" the engine. As a very cheep solution i squirted wd into the evap solenoid and verified the piston was closing. This is a normally closed valve and if you can flow air with the electrical plug off then it's stuck open allowing fuel vapor to enter.

also submitted NHTSA on my Hybrid for similar issues. #10897339 Update 9/10/16: See link below for info regarding my simple fix for stalling/starting problem. Evap purge control solenoid valve was sticking open causing constant pulling of fuel vapor into intake manifold. http://fordfusionhybridforum.com/topic/11235-fusion-stalls-and-loses-power-at-highway-speeds/

The owners manual says not to put any additives in the fuel that have metallic compounds. Other than that sounds like fair game. Pg.288 Ford Fusion Hybrid Manual "Choosing the right fuel Use only UNLEADED fuel or UNLEADED fuel blended with a maximumof 10% ethanol. Do not use fuel ethanol (E85), diesel, methanol, leadedfuel or any other fuel. The use of leaded fuel is prohibited by law andcould damage your vehicle.Your vehicle was not designed to use fuel or fuel additives with metalliccompounds, including manganese-based additives.Note: Use of any fuel other than those recommended may causepowertrain damage, a loss of vehicle performance, and repairs may notbe covered under warranty."

The above throttle body did not fix my stalling problem. Its actually a not-restarting problem. I replaced the Fuel Pump module relay next for 65 dollars from ford. Part #aa8z9d370b So far so good. I will report if problem persists. Edit 8/23/2016 Problem persisted. The FFH finally threw a code today while traveling on the interstate. P1450. This code relates to the EVAP system. Oreilly's was able to supply me with the diagnostic for this code. I was able to trace the problem back to the EVAP canister purge solenoid. This solenoid is very close to the throttle body. This valve is a normally closed valve so with the engine running and the wiring unplugged there should be no vacuum on the top inlet tube. If there is vacuum on the top port the valve is stuck open. I removed the valve and confirmed the valve was open as air would pass through from one port to the other freely. I removed the valve and squirted WD in both ends then beat on it a little. After massaging her a little the valve was now in the closed position. Once again i will report back if all is not well. At a minimum the permanent vacuum leak was fixed, for now. Would have been nice if a code was thrown earlier. My fault for "parts replacing". Could have cost next to nothing to fix. Update 9/10/2016: Since cleaning purge solenoid the car has not stalled or had any starting problems of any sort. If you start experiencing problems with car not starting after fueling the problem may lay in the evap solenoid. Fuel vapor floods the intake manifold and displaces oxygen which prevents car from starting.

After replacing the throttle body it did not solve my problem of the engine not starting after the hybrid system shut it down during coasting. I have since replaced the fuel pump module/relay that is in the trunk on the driver side behind the carpet. Ford Part #aa8z9d370b This is a $65.00 part and takes five minutes to replace. It had zero problems restarting the rest of the 750 mi trip. I will report if problem persists. Update 9/10/16: http://fordfusionhybridforum.com/topic/11235-fusion-stalls-and-loses-power-at-highway-speeds/ So far evap purge solenoid valve sticking was causing my stalling/starting problems. View above thread for details.

Not sure it has anything to do with dirt. Guessing the electronics within the throttle body are failing. This video shows a breakdown of the throttle body. They are the same throttle body as other non-hybrid fusions. https://www.youtube.com/watch?v=FDpUo3UPmto I replaced mine in about ten minutes and $100 part from ford.

Update 8/23/16 throttle body did not fix problem. See next post. I just had a similar experience. Within the last three days my 2010 fusion hybrid has quit three times. Two of those times were on the interstate. I researched similar problems with non-hybrid fusions and decided to contact ford regarding any potential extended warranty. There is no extended warranty for my vehicle as of yet. The dealer wanted over $300 to replace a $100 part(throttlebody). I decided to replace the part myself. I had the old part off within 5 minutes. And the new part was on in less time. I did not do the throttle reset and calibration procedure and as of this writing I have not been able to recreate the problem. I don't have many miles on the fix but will keep the forum updated.
