Something is wrong.
Purple tops are low impedence.
Purple tops should also be rectangular plug.

Red tops are high impedence.

These color combinations are for stock FC injectors only.

The only purple top, high impedence fuel injectors I know of are 850, side-feed injectors that FD's run as secondaries.
