searching brought up a lot of threads regarding the spark plugs being stuck in the cylinder. but i can't even get to that point yet. the nuts holding the ignition coils are rusted onto the stud. when i try to loosen it, the whole stud comes out. which i thought would be fine, but i still can't get them free. even though it feels like the stud is loose, it still feels like something is holding it in place. i was just going to try to pry it out, but i'm not sure what is on the back end holding it in place (as i don't want to damage anything). anyone have any insight on this dilemma? i'm just stuck at this point.

 

Did you find a good solution? I'm having the same problem with my 2003 Ram 1500 4.7L. Once the stud is exposed I tried grabbing it with a vise grip but it isn't strong enough to hold the stud while I try to unscrew the nut. My best idea is to pull the intake manifold with the coil packs still attached and then I can get to the plugs (and have better access to the studs so I can hopefully get those nuts loose).

 

So is the issue separating the nut from the bolt, bolt from the block or the coil pack from the spark plug?

 

This is an issue separating the nut from the bolt. The nut that retains the coil pack is corroded onto the bolt. This bolt also serves to hold down the air intake. When you take the coil pack off (assuming you coul get the nut off) it exposes a second set of wrench flats that you turn to loosen the bolt from the intake. This bolt is captive to the intake so you never fully pull it from the intake. Once you loosen all of them, you take the intake off and they travel with it. The issue is the first nut which retains the coil pack is so rusted to the bolt that when I try to loosen it, it turns the entire bolt and it unthreads from the intake and because it's captive, you can't just pull it all the way out so you still have the coil pack connected (loosely) to the intake. A picture would probably help but I'm not in a spot to take one now.

 

Sorry for the delay, so it can suck but saturate that puppy in brake cleaner, multiple applications over a day, compressed air can help push it in. It maybe enough.
