How do I best remove an ignition coil that is stuck?
What is your question?
Changing plugs today and cylinder 1 and 2 no problems, got to 3 and coil and plug covered in oil (assuming a valve cover gasket issue) and then #4 removed coil bolt and lifted up and coil tube would not come out. Only raised about 1/2 inch from seat. I twisted, pulled, prodded but it would not budge. Even sprayed a little WD40 down tube. I am afraid to apply leverage with screwdriver shafts or channel locks in fear of breaking off plug. Any suggsetions on strategy? Cant replace valve gasket until I get this coil free as well. Thanks for any adviee. PS: I went ahead and replaced plug in 3 and reseated coil and old plug in 4. The car cranks and after reset no maintenance light but still need to fix/replace it just keeps my wife on the road at least.

Lift the coil as far as possible and spray a BUNCH of WD-40 down beside the rubber boot... Keep working it up/down while twisting.. Compressed air from a shop air compressor can be injected with a blow gun down beside the plug boot and 'most' of the time it will pop the coil right out!!.. Ok now, so you brake the plug, no big deal.. Just remove everything from plug well then remove the rest of the spark plug!.. If coil gets damaged.. Replace it also.. .. You do what you got to do!!!!
