Thanks for the input bud. Not sure if the plugs and cop's are original. We bought it with 18k and have not changed them myself so my guess is they are. No Cel yet. Also checked the kam and nothing stored. Not sure how the system is on the edge but in my F150 you can experience low grade misfires to a degree that the truck is under powered and bucking and it still will not throw a dtc. I have on numerous occasions had to press it for a few miles to misfire just to get it to kick the cel to give me a cylinder number to work with. If these coils are built anything like the cop's I have in my truck, a resistance check will only show a primary failure in the winding. As far as I know, if it wont provide a dtc, low grade misfires can only be picked up running live data mode 6. Battery is 1.5 years old. Haven't had it tested but no other sings of it being weak. I want to change the plugs at the least as standard maintenance. But If I'm going to go tearing the intake manifold off to do that, might as well throw a new set of cop's. I hope it's no gremlin in the trans. That's always the first thought for most. But in many cases ends up being a misfire (fingers crossed) It has all the tell tale signs of a low grade misfire from what I can tell. Shows up more under load and right after the shift into OD when the rpms are in the lower 1.5k range. Slight random bucking every few seconds. I'll poke around for a set of oem quality cop's or may just bite the bullet and pick up motorcrafts. Hope that fixes it! Thanks for the info again.

Hey guys 07 AWD SEL 3.5L, 85k miles Started to notice a slight misfire. Individual bucking feeling every few seconds. No CEL or flashing CEl. Seems to be random at different speeds but mostly under load with lower rpms in the 1500 range is most noticeable. Ive read the stories of pcm's causing coils to burn up and bad coils burning up pcms... not sure which is true but either way one of them is and from my research it seems to lean more toward a bad coil leading to a bad pcm which in turn can cause other coils to go bad. So, before the misfire gets any worse Id like to replace all of the coil's and plugs and cross my fingers. Question is, other than OEM motorcraft parts, are there any reputable ignition coil manufacturers to buy coils at a lesser costs for the 3.5L? For instance, being an F150 owner for the last 15 years I know that Visteon used to manufacture ignition parts for FOMO and makes oem quality ignition coils for the modulars and have held a good review for many years. I know to stay away from all the other ebay chinese manufatures, ive had bad experience with global cop's, and accell. Is there another option or am I heading to the dealer for new parts?
