P0300 Code & Fuel odor
Well I posted a few months ago when I started throwing this code. I haven't had much time over the last couple of years to play with the Z and I need some help.
Symptoms: Rough idle, heavy fuel odor, intermittent backfire.
My Z is a 2003 I/C Mag, LG LT headers with HF cats, B&B Bullets, Hurricane air intake. All coils, plugs, wires are still stock. Any help is appreciated.
Mahalo!

No but I should with the fuel odor being so strong. I am guessing that the O2 went out and the driver side bank is getting excess fuel dumped into it but I was hopeful someone had a similar experience and could point me in the right direction.

I have no first hand knowledge with this but from the manual, there is lots to look at.
DTC P0300
System Description
The powertrain control module (PCM) uses information from the crankshaft position (CKP) sensor and the camshaft position (CMP) sensor in order to determine when an engine misfire is occurring. By monitoring variations in the crankshaft rotation speed for each cylinder, the PCM is able to detect individual misfire events. A misfire rate that is high enough can cause the 3-way catalytic converter (TWC) to overheat under certain driving conditions. The malfunction indicator lamp (MIL) will flash ON and OFF when the conditions for TWC overheating are present. If the PCM detects a misfire rate sufficient to cause emission levels to exceed mandated standards, DTC P0300 will set.
Conditions for Running the DTC
DTC P0101, P0102, P0103, P0106, P0107, P0108, P0116, P0117, P0118, P0125, P0128, P0335, P0336, P0341, P0342, P0343, P0410, P0500, P0502, P0503, P1114, P1115, P1120, and P1220 are not set.
The engine speed is between 425-3,000 RPM.
The ignition voltage is between 10-18 volts.
The engine coolant temperature (ECT) is between -7 and +130°C (19-266°F).
The fuel level is more than 10 percent.
The throttle angle is steady within 1 percent.
The antilock brake system (ABS) and the traction control system are not active.
The transmission is not changing gears.
The A/C clutch is not changing states.
The PCM is not in fuel shut-off or decel fuel cut-off mode.
The PCM is not receiving a rough road signal.
Conditions for Setting the DTC
The PCM is detecting a crankshaft rotation speed variation indicating a misfire sufficient to cause emission levels to exceed mandated standards.
Action Taken When the DTC Sets
The control module illuminates the malfunction indicator lamp (MIL) on the second consecutive ignition cycle that the diagnostic runs and fails.
The control module records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the control module stores this information in the Failure Records. If the diagnostic reports a failure on the second consecutive ignition cycle, the control module records the operating conditions at the time of the failure. The control module writes the operating conditions to the Freeze Frame and updates the Failure Records.
Conditions for Clearing the MIL/DTC
The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
Clear the MIL and the DTC with a scan tool.
Diagnostic Aids
Excessive vibration from sources other than the engine could cause DTC P0300 to set. The following are possible sources of vibration:
Variable thickness brake rotors--Refer to Symptoms - Hydraulic Brakes in Hydraulic Brakes.
Drive shaft not balanced--Refer to Vibration Analysis - Driveline in Vibration Diagnosis and Correction.
Worn or damaged accessory drive belt--Refer to Base Engine Misfire without Internal Engine Noises in Engine Mechanical.
There may be more or less cylinders actually misfiring than indicated by the scan tool.
Spray water on the secondary ignition components using a spray bottle. Look and listen for arcing or misfiring.
If there are multiple misfires on only one bank, inspect the fuel injector and ignition coil, power and ground circuits for that bank. Refer to Engine Controls Schematics .
Test Description
The numbers below refer to the step numbers on the diagnostic table.
If the actual CKP variation values are not within the learned values, the misfire counters may increment.
DTC P0135 or P0155 can be set because of a misfire.

STL94, I thought so as well. I did see on the OBD guide I was looking over that a faulty O2 could also activate the same P0300. Hopefully, get this sorted ASAP. I'll post up the solution.

Thats not a backfire your hearing, it's raw gas exploding in your exhaust.
The diagnostic information that the C5 is capable of displaying will only be able to show a P0300 code, get a real scanner and hook it up to your car and it will be able to isolate it further by showing a P030X code, the "X" will be the cylinder thats misfiring.
If the scanner is still showing a P0300 code then you do have multiple cylinders misifiring and you'll need to start checking plugs, wiring and possibly coil packs.
While a bad O2 sensor can eventually cause a misfire and P0300 code, I don't recommend following the shotgun approach to troubleshooting.

Typically random misfires are plug/wire/injector related. If you've changed wires and plugs, probably time to clean the injectors and check them for leaks with a pressure guage. They should hold pressure after you shut the car off, if you've got "leakers" those cylinders will run rich because of the leaking fuel in those cylinder(s). If the car has a lot of miles, you can send them out to be hydrostaically cleaned and their flow measured before and after. www.cruzinperformance.com did some for me and posted the flow #'s on his site. You can have them all cleaned and rescreened for less than the price of 1 new injector.

Just wanted to post up the solution to the issue, and yes, I only finished working on it today.....I've been busy.
Swapped out original plug wires with GM Performance wires from Bob Fitchner Chevrolet (Who was AWESOME TO DEAL WITH), and swapped the stock plugs for NGK V-Power TR6's gapped at .40. Closed everything up and fired her up after sitting since September.
No fuel odor and she ran like she used to. I'm grinning ear to ear again! Thanks to everyone who helped in trying to zero in on the issue.

What is/are the code/s this time?
P0300 is random/multiple misfire.
You may want to try a good OBDII code scanner to get the freeze frame data (conditions when it sets the code)
Random misfires that jump around from one cylinder to another (P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open.
Other things to check...
coil packs
injectors
vacuum leak/s
Even more things to check...
oxygen sensor/s
cat/s
valves

If your O2's were on the way out, you'd probably have more codes dealing with the O2's. I would suspect leaky injectors or malfunctioning Fuel presuure regulator. Did you throw a guage on the fuel line schrader valve to see what the pressure is? Keep the guage on the fuel rail and shut the car off, it SHOULD hold pressure for quite some time, if it leaks down quickly, you have a stcky injector hanging open.

EFI-1, I had the PO300 code immediately after installing headers/hi-flow catted X-pipe and vararam cai. Had all the symptoms you described as well. I let it cool down for a day, then went around and checked everything I touched during installs. I found a loose clamp on cai bellow allowing outside air after passing maf sensor. Also found loose clamp on master cyld brake booster hose, creating vacuum leak. I tightened the clamps and made sure all connections to coils, plugs, o2 sensors, etc. were correct, and fired up car and it ran fine with no problems. Hope this helps, Mike.
