As I said above I am getting a P0355 & P0356 from my Scan Gauge. These codes are referring to cylinders 5 and 6 which I do not have. Does anyone have access to a Chevy factory manual that may give a different explanation for these codes? @Ma v e n @Robby @Valpo Cruze
This is what I have found so far:
P0355 - Ignition Coil E Primary/Secondary Circuit Malfunction
P0356 - Ignition Coil F Primary / Secondary Circuit Malfunction
Both P0355 & P0356 are generic codes, so they can have several triggers. Here are the most common:
I have recently had my timing chain replaced.
Both Camshaft sensors have been replaced. I also have a new crank sensor but did not install it.
A new coil pack and plugs were just installed. This issue occurred after the timing chain and sensors were replaced, but before the coil and plugs were.
I am tuned.
Current symptoms:
Often when I start the vehicle, the starter runs on more than normal before it starts.
Occasionally it runs on until it just stops. I assume there may be a limit on how long the ECM will allow a crank condition.
When I get on the throttle, it slowly winds out until redline and shifts and repeats. Normally this would occur much quicker and now I sometimes feather the throttle as I am afraid it will over rev.
Once I am at speed, everything seems normal.
EDIT:
I was driving along, came to a stoplight and the motor just stopped. It did however start right back up. This was about four days ago.
i have also pulled the ECU plugs and found no corrosion. See pictures below.in post #9.
Possible solutions (guesses) I may have found so far:

Any and all suggestions appreciated.

Both P0355 & P0356 are generic codes, so they can have several triggers. Here are the most common:
- Defective ignition coil (COP)
- Wiring issue
- Short to voltage or ground on COP driver circuit
- Poor connection
- Open on COP driver circuit
- Loose connection at coil or broken connector locks
- Faulty PCM
