Hi all, I've got a misfire on this car. Got the code read and it was the P0300, random misfire. Replaced all 4 plugs, and still had the same problem. After I replaced the plugs, I pulled them out again to take a look at them. Cylinders 1 & 4 were covered in gas, and looked clean, while the center 2, cylinders 2 & 3, were covered in carbon and looked like they had fired. I suspect I need to replace the coil, and was wondering a couple of things. First, does the coil sound like the main suspect here? I think the fuel system and a vacuum leak have been ruled out, but want to make sure before I spend the money to replace the coils. Second, is there any way to test the coils on this car? Thanks in advance for your help.
