Error Code P00355 on Scan Gauge

[mtenderenda]

Hi guys,
Today i was driving down the highway, noticed the check engine light come up. Prior to it coming up, I noticed that the car sputters when I am cruising at a constant speed. Wondering if the injectors are clogged, electric, fuel pump or fuel filter. I have a underdrive pulley setup, JLT air filter, Denso plugs and after market coil packs. And on top of that, I have not driven the car alot. Its been in the garage. I take mass transit into work

Probably the coil packs, there have been many issues with them, especially on Cobras

So what's the next step? Should I swap them around?

P0355 is definitely trouble code for coil packs. I would put the stock coils back on.
