HI tuneserv,
What makes you believe the vehicle is going lean? How many kms on the clock? What's the compression like?

    Have you tried opening the fuel feed screw on the pump while having the afr meter connected and see what difference it makes?

My check engine light is on. it is pulling 4 codes P0302 P1670 P0174 P0171


code p 0302 is a misfire on no 2 cylinder
check that the plug lead is on properly, that the lead is operational
move the injector from 2 to another cylinder and see if the misfire follows the move
code p 0174 refers to system too lean bank 2===causes intake /exhaust leak---fuel pressure / pump---injector/s--AIR system--hose connection/s
code p 0171 refers to system too lean bank 1=== causes intake /exhaust leak---AIR system---MAF/VAF sensors---fuel pressure / pump---injector/s -- HO2S
You stated that you replaced the O2 sensor but that is different to the HO2S sensor , does a different job and controls the air/fuel mixture from the ECM
because it has banks 1 and 2 it is a v engine and you will have a HO2S in the exhaust manifold or before the cat converter for each exhaust
O2 sensors are after the cat converter and confirm the HO2S settings for the ECM
to put the lights out , use a scan tool to reset the ECM

97 Grand am v6 up & down idle. Driving =steady acceleration. I've changed, O2 sensor, throttle positioning sensor. Scan is still saying Random misfires? Get warm won't start.


P0300 Random misfire - lean condition , vacuum leak , low fuel pressure , fuel filter plugged partially , mass air flow sensor .
If the misfire is random, check for the following conditions:
?€¢
System Grounds: Ensure all connections are clean and properly tightened.


?€¢
MAF: A Mass Air Flow (MAF) sensor output that causes the PCM to sense a lower than normal air flow will cause a lean condition.


?€¢
Air Induction System: Air leaks into the induction system which bypass the MAF sensor will cause a lean condition. Check for disconnected or damaged vacuum hoses, incorrectly installed or faulty crankcase ventilation valve, or for vacuum leaks at the throttle body, EGR valve, and intake manifold mounting surfaces.


?€¢
Fuel Pressure: Perform a fuel system pressure test. A faulty fuel pump, plugged filter, or faulty fuel system pressure regulator will contribute to a lean condition.


?€¢
Injector(s): Perform injector coil/balance test to locate faulty injector(s) contributing to a lean or flooding condition. In addition to the above test, check the condition of the injector O rings.


?€¢
EGR: Check for leaking valve, adapter, or feed pipes which will contribute to a lean condition or excessive EGR flow.

Reviewing the Fail Records vehicle mileage since the diagnostic test last failed may help determine how often the condition that caused the DTC to be set occurs. This may assist in diagnosing the condition.

What are the probable causes of DTCs P0300 and P0316?


code p 2274 refers to heated oxygen sensor(HO2S) 3 bank 1 signal stuck lean or oxygen sensor(O2S) signal stuck lean===causes for both--wiring ---HO2S--fuel pressure --injectors --intake leak
code p 0300 refers to random /multiple misfires detected ===causes --spark plugs -- HT leads injector/s--ignition coils --low compression --wiring
code p 0316 refers to misfire detected during start up---first 1000 revolutions ===causes --engine mechanical fault---wiring---ignition / fuel system---injector
in all codes the injectors show up as a problem cause and if you couple that with low fuel pressure issues you may have a pointer to the real cause
have a pressure test done on the fuel manifold top check for pump fault , filter blockage and faulty pressure regulator
check /clean injector tips as they could be suffering from contamination problems and not operating freely ( good fuel injector cleaner)

Have you checked/replaced the O2 sensor(s). They produce the data that your computer reads. Bad/clogged O2 sensors will trick the ECU into running lean/rich.

Code p0157


DTC P0157 HO2S Circuit Low Voltage Bank 2 Sensor 2

Check for the following:

HO2S wire - Sensor pigtail may be mispositioned and contacting the exhaust manifold

Intermittent ground in the wire between the connector and the sensor

Poor VCM to engine block ground

Lean injector(s). Perform Fuel Injector Balance Test for the 5.7L or the 7.4L.

Fuel contamination. Water, even in small amounts, near the in-tank fuel pump inlet can be delivered to the injectors. The water causes a lean exhaust and can set a DTC P0151

Fuel pressure. System will be lean if pressure is too low. It may be necessary to monitor fuel pressure while driving the vehicle at various road speeds and/or loads to confirm. Refer to Fuel System Diagnosis.

Exhaust leaks. If there is an exhaust leak, the engine can cause outside air to be pulled into the exhaust and past the sensor.

Vacuum or crankcase leaks can cause a lean condition and/or possibly a high idle.

If the above are OK, it is a faulty HO2S.

Never solder the HO2S wires.

I HAVE A P0300 OBD CODE I DID A COMPRESSION TEST TO ENGINE AND IT PASS THE TEST,I DID CHECK EGR VALVE,CHANGE SPARK PLUGS,IGNITION WIRES, CAP AND ROTOR, I DID CHECK TPS SENSOR MAF SENSOR,FUEL PRESSURE,AND...


p 0300 code is for random misfires
random misfires are more from dirty /faulty injectors or low fuel pressure than anything else
have a pressure test done to check pressure regulator , filter and pump operation
use a can of quality injector cleaner or remove and clean the injectors

Try some injector cleaner in order to see if the lean condition improves. Lean conditions can sometimes be caused by o2 sensors or other sensors that are not within specifications.

Vibration problems in 1kz te


Check calibration. Muffler supports from the front till the back, there should be proper clearance. Is your diesel fuel of proper cetane rating for the engine? Check your belt drive system, is there any part that is excessively draining engine power, power steering pump, air con compressor, alternator or generator? Do these preliminary steps and isolate.
