UPDATE; well its been a couple months 2,000 miles added.. The problem remains at between 1400-1900rpm in high gear... when applying pedal to increase speed slowly.. the engine will misfire.. although not as severe as before #6 coil was replaced.. but it will still do it once or twice until rpms goes above 2000 or so.. If too much pedal is applied , enough to make engine change to lower gear, it will not do this.. It also seems to do this most noticeably, when traveling up an incline.. For a while I thought this misfiring was limited to a certain speed range.. 45-60 mph when in high gear and applying pedal . . but I have noticed it misfiring at 70-80mph... but always in that 1400-1900 rpm range in high gear.. For a while I was disengaging OverDrive which kept the engine rpms higher most all the time, but noticed when in heavy traffic or slow moving traffic jams if I applied the soft pedal in that rpm range it would misfire as well.. Question; I realize the problem may be the pcm , but without going that far yet, is it possible some of the other coils are fried other than the #6 and by replacing those problem could be resolved ? Can I swap out these coils myself ? The front side ones seem they would be able to do , the backside ones a little harder to get too.. Does there need to be any flashing or programming done to the computer when replacing these coils afterwards ?

after a few days the symptom remains.. as stated before they replaced the #6 coil right after I purchased it due to this engine misfire which was very apparent , sometimes missing 5-20 times in a row.. after the replacement coil it seemed to go away, didnt notice it for several days but Ive noticed it 8-10 times since then, always down at low rpm.. 1100 or so.. I suspected perhaps the aftermarket stereo (450W Kenwood, high quality) amplifier putting too much draw on the electrical system, but the problem has occurred several times without the stereo being on at all. It only jerks/misses once in a while now, which is much better than before but still very noticable and annoying. I have read replies here about 'flushing' the pcm , and also replies stating the spark plugs were also replaced when the coils were replaced.. I have bought Toyotas and Mazdas for the past 18 years without ever having even a single problem.. brakes and tires thats it.. My first ford experience so far is not a good one.. I test drove another 2007 edge the same day on the same dealer lot and did not purchase it because I noticed this EXACT problem, but did not notice it on the one I bought.. but sure enough same issue.. Now having seen the numerous posts of this exact issue on this and other forums, does not leave a very good impression on ford edges or ford in general.. Dont know where to turn from here but I simply cannot afford thousands of dollars of repairs for a vehicle I paid a good penny for..

youre correct... I did this before I had the coil replaced last week... turning the OD off doesnt allow the rpms down to the 1000-1200 area... and it doesnt do it.. I too got in the habit of turning it off before my trip.. but I dont want to do this every time I drive the vehicle due to using more fuel... Im really curious if this stereo system is messing with the electrical system.. could it cause overloads of some sort.. or is this coil issue common on ford edges.. I cannot afford to spend money on these issues especially if they keep reoccurring. Just bought it last week... vehicle is in GREAT shape in and out, only problem is this jerk/miss that seems to have started happening again... Is there anything I can do at home to reset a module, etc.. surely the coil they replaced last week isnt bad already ??

well on the way home tonight (after about a week with no jerks or issues), I noticed a single miss/jerk at 1100rpm again.. fwiw, Im curious about the following; as stated before, its a used 2007 ford edge 83K miles.. On the way home today I was running the AC/MAX fan fullblast.. Also, the stock radio had been replaced before purchase with an aftermarket system DVD player with the addition of a subwoofer box (2 12' subs) powered by a 120W amplified which is in the cargo area.. I was jamming the radio at the time and the woofers had been thumping pretty good... as well as the AC on max.. could these be any factor in this coil issue.. too much draw on the electrical or something of this sort.. The problem so far isnt as severe as before they replaced the #6coil last weekend.....yet... but it was definately the same miss/jerk I felt.. Thanks again CHall

yes dealer paid for it.. $330 . . happy he stood by his vehicle. runs great now..

Neither of the driver side Dash A/C cents come anywhere close to aiming at the drivers face.. The Inner and outer vents both shoot air at best to the shoulder area...and even then I must lean over to feel it.. The air flow is weaker than ever other car Ive had in the past but I could live with that if I could just aim them at my face.. especially on hot days.. The ones in my 2007 are the standard vents for that model year.. horizontal slots with up and down adjustment.. Ive heard later model years had vertical slots that had better aim and the ability to close them off entirely.. Ive taken the dash assembly off and can see how easy they would be to replace.. Anyone know where I can get these 'same size' verticals ? and do they allow better aim ? Dont want to pay top dollar for them from a dealer if possible but will if I have too.... thought maybe there was an aftermarket replacement perhaps ? Thanks.. C Hall

dealership replaced #6 coil. all is well in the world. Love this car. runs like a dream now.. thanks for your replies.. spot on.

thanks so much. will inform dealer tomorrow of this....

Just bought a used 2007 edge this week.. 83K miles... engine seems to run fine.. no noises, leaks, or obvious issues.. however.. when at low rpm usually around 1100-1500rpm and i apply slight throttle the car will 'miss' or 'jerk' sometimes just once sometimes several times in a row.. its very obvious at 60mph @ approx 1100rpm coasting.. then applying slight throttle (not enough to engage a lower gear or rev up to 2000 or so...) but just easy throttle.. it will jerk several times until I reach 1800rpm or so then it seems to do this less.. I drove to work with overdrive disengaged this morning..the engine rarely fell below 2000 the whole trip and I didnt notice this problem... on the way home I left the overdrive engaged as usual and at low rpms it would do this every 10 secs or so... sometimes a single 'jerk' sometimes several...I lose forward movement during those quick jerks.. some of these slips are somewhat violent especially at 60-65 shaking the car slightly.. definately noticable. dont know if this is the transmission or electrical...or fuel... having the dealership where I bought it look at it tomorrow.. but it IS NOT under warranty.. I did not notice this at all during 2 test drives, but dont believe I ever got up to 60mph or so either time... as soon as I drove it home on the highway I noticed it immediately.. any help or comments appreciated, C Hall Louisville, KY.
