5vz-fe misfire codes

Nice info but what's your question ? You have a Oxygen Sensor Circuit Slow Response (Bank1, Sensor1) code P0133 , an you have P0171 System Too Lean (Bank 1) ! You have a bad O2 sensor , vacuum leak , Test O2 Sensor mov

sounds like a faulty fuel pressure regulator, i checked out code P0171 and that is correct.
good luck,
frank

Diagnostic Test Code (DTC) P0316 means that a cylinder misfire was detected within the first 1000 revolutions of the engine crankshaft after engine startup. This code will always be stored at the same time with freeze frame data and a fault code for the offending cylinder.
This is where DTC P0305 comes in.
This code means that cylinder #5 is the cylinder that is causing the misfire.
Coils and plugs are only two of the many possible reasons for a cylinder misfire.
The possible reasons for both of these codes are:
> Damaged crankshaft position sensor
> Ignition system (Primary or Secondary)
> Faulty fuel injector or fuel injector control circuit
> Poor fuel quality (will usually cause MULTIPLE cylinder misfire codes)
> Base engine faults (burned valves, low compression, damaged lifters or cam, blown head gasket, etc.)
> Damaged/malfunctioning PCM

NOTE: The LEAST LIKELY cause is the PCM. A damaged Crankshaft Position Sensor will usually cause problems on ALL cylinders, not a single cylinder, however it IS possible if the sensing ring is damaged.

P0302 is a misfire in cylinder #2. When was the last time you changed spark plugs? That's the most common cause of a misfire.

Because you got a misfire on cylinder #1 PO301
A misfire on cylinder #2 PO302
Misfires first 1000 rev PO316
O2 Codes PO 174
Etc,Etc


The LTT, is the result of not learning (yet-thus long term)
what isn't working correctly---Your Engine

Replace bad Coil--which ever is missing
Do not go by the codes,alone ,TEST

these are hard to diagnose. First trace evap hose from fuel tank to evap cannister. Check for cracks in hose or loose connections. Check out cannister for cracks. Also check hose from cannister to intake manifold. If hoses are good, it may be leaky purge valve. Hope this helps.

Testing your OBD2

Before You Begin
Since all vehicles are not the same please refer to the manual supplied with the OBD2 code reader for vehicle specific instructions.
Is your vehicle compliant?
All cars and light trucks manufactured since late 1995 should be OBD2 compliant. Two factors will show if your vehicle is definitely OBD2 equipped:

• There will be a note on a sticker or nameplate under the hood: "OBD2 compliant”
• There will be an OBD2 connector as shown below

Pin 2 - J1850 Bus
Pin 4 - Chassis Ground
Pin 5 - Signal Ground
Pin 6 - CAN High (J-2284)
Pin 7 - ISO 9141-2 K Line
Pin 10 - J1850 Bus
Pin 14 - CAN Low (J-2284)
Pin 15 - ISO 9141-2 L Line
Pin 16 - Battery Power
Where is the connector located?
The connector must be located within three feet of the driver and must not require any tools to be revealed. Look under the dash and behind ashtrays.
Important info about OBD2

• Can diagnose/check engine problems in all CAN and OBD2 vehicles (1996 and newer) and many of the most popular OBD1 (1981 to 1995) vehicles
• Features unique patented all-in-one screen display and LED display for quick emissions check
• Automatic refresh updates data every 30 seconds when connected to the vehicle - an easy way to verify repair completion
• Code definition can be displayed in English, French and Spanish
• Can be Flash updated with a standard Windows® PC
• Features memory/battery backup for off-car review and analysis

Connecting
Connecting the OBD2 Code Reader is as simple as locating the DLC connector. The DLC connector is usually found under the driver side (left side) of the dash. The cable attaches only one.
Reading the LCD Display
Click to enlarge
Before you start testing, take a good look at the LCD display. The illustration above explains what the various icons mean and how the DTC (Diagnostic Trouble Code) will be displayed. The unit is self-powered by three-AAA batteries and will let you know when they are running low. When connected/receiving power from the vehicle, the CAR Icon will display.
The OB2 code reader is a very simple tool to use. Once it is connected, turn the power on. Once the ignition is switched to the on position, the code reader is checking the system for any stored DTCs.
The meaning of each DTC can be found in the manual supplied with your code reader.

Example: the code reader displays a DTC PO309, Cylinder 9 misfire was detected.
P0298 Engine Oil Over Temperature P0300 Random/Multiple Cylinder Misfire Detected P0301 Cylinder 1 Misfire Detected P0302 Cylinder 2 Misfire Detected P0303 Cylinder 3 Misfire Detected P0304 Cylinder 4 Misfire Detected P0305 Cylinder 5 Misfire Detected P0306 Cylinder 6 Misfire Detected P0307 Cylinder 7 Misfire Detected P0308 Cylinder 8 Misfire Detected P0309 Cylinder 9 Misfire Detected P0310 Cylinder 10 Misfire Detected P0311 Cylinder 11 Misfire Detected
Once you know what the problem is, you have to determine what's causing it. In this case the intake manifold gasket was faulty. Once the repairs have been made, it is time to clear the DTC and check the system to verify the repair.
Clearing the Diagnostic Trouble Code (DTC)
Clearing the DTC is very simple. Press the ERASE button on the code reader. A message will display on the screen; "SURE" for conformation. If you wish to clear the DTC press and hold down the ERASE button again until a message appears on the screen "DONE". If you did not wish to clear the codes and hit Erase by mistake at the screen message "SURE" simply press the link button to return without erasing any DTCs.
When you clear the DTC(s) from the PCM (Power train Control Module)you also clear ALL of the other gathered information that the PCM has collected, including Freeze Frame, Drive Cycle data, manufacture specific enhanced data end everything stored in memory is erased - just like if you cleared the Cache files on your PC.
The vehicle's PCM will need to re-learn the information that was erased. Don't be alarmed!! This is easily accomplished just by driving the vehicle. All you have to do is get driving.

Good luck and check the OBD 2 connection port.

make cranshaft gear has not spun under timing cover ive seen it happen before

Replace the coil pack..

Replace the coil packs.
Your issue is NOT the converter, or you would have a P0420/P0430 code
