Pre-issue:
Not sure what happened yesterday, but I ran the tank almost dry and had to fill up at a station I normally do not frequent, but I filled up with 93 octane premium just the same.
I use my Scan-Gauge to record my fuel ups and it tracks fuel usage for me. It is usually within a few 10ths as far as accuracy is concerned. After fueling up, I entered the data and low and behold, it is a little over 4 gallons off.
More importantly, twice on my way to the station the engine dropped out and caught back up, kind of like a hiccup. It also was acting kind of goofy when I stepped on the throttle and due to circumstances had to immediately lift off the throttle. I continued on to my destination and parked for about an hour and a half. When I returned and tried to start the car, it turned over continuously for about 20-30 secs before I shut it off. It tried again about a minute later to the same end. Finally after the third try it started.
Main Issue:
When I got home, I had been thinking about the age of my coil, when the last time I checked the plugs and the TSB about the coil pack connector. So I thumbed the buttons on the Scan-Gauge and brought up the code screen. I now am the proud owner of both P0355 and P0356. That in and of itself is confusing as they point to coils five and six. I had always thought that I only had four cylinders, but in altered reality you know...
I do not know if these codes are related to the rest of the story or not, but I have included the info just the same.
How can I tell if it is the coil pack or the connector plug? Is there a way to test either? I have read that you can test the signal to the coil using the Hertz setting on a multi-meter and the signal should be between 5-20hz, but I do not know what wire i should target. Any thoughts?
It is currently running fine, but I did not like the feeling of being stranded even though it only lasted a few minutes?
TL;DR
Car cranked excessively multiple time before starting
Threw Codes P0355 and P0356

P0355 is a generic OBD II diagnostic code that indicates an issue with the ignition coil “E” or "5". Specifically with the primary or secondary wiring circuits.
P0356 is a generic OBD II diagnostic code that indicates an issue with the ignition coil “F” (the sixth cylinder). Specifically with the primary or secondary wiring circuits.
