lol it's every time I accelerate, and when there's a cop near by it's a different sound and light.

You're getting RF from the new coils. The wires just aren't able to suppress the radio interference the higher voltage coils tend to make. Try to look for plug wires that can suppress that RF, should help.

ok, well the only problem is that I don't have plug wires. My car has Coil On Plug ignition.
