So this wire is under the coil bracket bolt on the back by the fire wall? I just took my coil packs off and left the last bolt out think this is my light problem?

So how long did that first MSD coil last that was leaking? You ever get an SES light after you installed those coils?

I had this problem on my 99 at one point.. the o2 connectors where dirty. used electric parts cleaner and sprayed them out. Put them back together and i have not had the problem sence.

I thought a flashing SES meant dead misfire?
