both the original coil and dizzy was bad! i bought 2 dizzys just to be safe, less trips to the boneyard. not sure i have the timing where i want it motor is running funny, i suspect a vacum leak or bad iac. did a motor flush, waiting for my friend to come back with a magnetic drain plug. then im putting in full synthetic. hopefully this will help my ignorant actions of porting the heads like a dumas.
