This coil is off A 2007 EGC, after I took it off, I noticed it was wet below the rear spark plug wire hole, and when I turned it on its side is when it started to bubble, I assume this is not good and it is time to replace it, I did some looking and I found the prices anywhere from $60.00 to $145.00 and .4 .45 .5 Ohm, so I turn you for help, #1 is the coil bad, #2 what brand name do you trust and #3 which Ohm is better.
