Flashing Check Engine Light????Missing real bad Ive been chasing down a really bad miss after my car warms up. I found a ignition fuse under the hood blown, replaced it and now my car is missing even worse and the check engine light is flashing??? I have replaced the coil and plugs, and am waiting on o2 sensors to get here sat. Has GMPP Opti with under 3k miles on it. What is the flashig check engine light? I could still drive my car before i replaced the fuse, now i cant because it miss's so bad.

U should change out your wires before o2 sensors cause it could be that not 02s and a check engine light that flashes means a misfire on one or more of your cylinders

Thanks for the input guys.
I changed all the plugs, the passenger side was solid black. turned out one of the o2 sensors wires was broken so i put new plugs and o2 sensors in and she runs great. just need a tune for the true duals now.
