Hey everyone,

Having some trouble with a 2017 Civic Sport 4 Cyl 1.5L (Manual) today.

It's been cold here, and we had a mini snowstorm last night. Went to start and warm up the civic this morning and had the following issues initially.

- Slow Start
- Low, unsteady idle.
- No Throttle Response
- Stall after roughly 10-15 seconds

After the initial stall, dashboard showed the following warning lights

- Check engine
- Brake System
- Power Steering
- Traction Control

On repeated start-up attempts, there was an even lower idle and faster stalling with zero throttle response.

After roughly 5 minutes of attempts, there was eventually a throttle response, with an improved idle (still not steady however) and no stall. Shut the engine down, tried again, died wont start at all.

Pulled the codes the next day
P0301, P0304, P0300

I got some misfires and replaced the spark plugs, but no joy. Here is how the car sounds now.

- No prior issue of any kind with the Civic
- 43k miles
- filled up the tank full the day prior.

What should I be looking at next? Thanks!

EDIT:

I swapped coil positions and rechecked the codes, still erroring on the same cylinders.
