P0300 Misfires Flashing CEL...But wait there's more!

Started with cylinder #3 misfires and replaced the coilpack there and new plugs all around. Now random misfires p0300 and plug #3 looks wet. Replace ionization module with spare no change.
Here is the ultimate clue. Engine light blinks on downhill coasting.
I hear a sparking/clicking noise near injector #3 or is that the throttle body?
I have a Tech2 and the misfires are:
cyl 1:5,000
cyl 2:20,000
cyl 3:30,000
cyl 4:3,000
obviously rounded off.
I have never seen blinking CEL coasting. Only hard acceleration. Is this a bad injector?
Thanks Saab braintrust.
