Hi guys

I've got a bugeye sti, stock standard. On the highway I gave it a squirt through second and third then cruised. I stopped at the lights and noticed a funny idle. Then further down the road the engine not sounded like it was missing. Then lost power on throttle. I limped it back home. On idle, the engine shakes, fuel smell from exhaust.
I'm guessing a dud coilpack. I've fixed this on other cars. But on my sti, I'm a bit confused. There is No CEL and i plugged in a obd scanner but no fault codes.

Will a dud coil pack throw a fault code?
