Is it the sensor of air in the fuel rail. Have the fault codes read.
Replace the faulty units with genuine one because most aftermarket units are not set for OEM cpu units and are not completely compatible

Hi, i want you to clean the air intake valve and idle speed control valve, follow the procedure below.

Here are the common cause of surges, cold stalls, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

The error P1130 and P1131 is for the fuel trim and lean fuel mixture respectively. This tells me that this may be an issue with the air fuel mixture or its reached its limits in compensating for the incorrect mixture. You could try to clean out the intake first using carb cleaner spray or tuner spray to clean out the intake and the MAF sensor which measures the air that comes in. Check also if there are leaks or gaps on the air duct found between the air filter and the intake manifold and the intake plenum. Leaks would cause the system to get an incorrect reading. If it were a faulty sensor you should get the error code for the sensor and you may have issues starting the engine up.

Check also the vacuum hoses which may be loose or cracked that needs replacing or refitting. This is also a common cause. I also do not rule out the possibility of the fuel sensors going or starting to go bad. The PCV may also need cleaning or replacing.

With all mentioned items go check first the leaks of the intake system and the vacuum lines as these are found to be common. Some leaks or cracks are minimal but is crucial to the sensors.

2005 2KD Hiace, starts lazy,revs good when it starts but accelerator goes dead, check light comes on, then in about 2 minuets the engine dies. 093 code.


fault code is missing a letter and first number
so its P0093 large fuel leak

the fault list has list of what to check
http://www.obd-codes.com/p0093

Fuel injector failure, Fuel line common rail leak, Fuel pressure sensor malfunction
Fuel pump or lift pump failure, Fuel heater constantly on Fuel temperature sensor failure ,

Leaks at any point in the high pressure circuit Electrical connector corrosion or seating problems
Fuel pressure regulator malfunction Fuel filter plugged dropping the fuel line volume Injector pump leak
Fuel control actuator failure
Cascade overflow valve malfunction Short in the electrical harness at the injectors or to the ECM Fuel pressure limiting valve ECM failure

I'm getting a code for low fuel rail pressure


you can try to erase the fault code with your obd2 scanner, after a period of time, check it, if you get the code again, you must take it to repair.

Diagnostic Test code (DTC) P0191 has a generic description which reads "Fuel Rail Pressure (FRP)Sensor Circuit Performance"

This code sets when the Powertrain Control Module (PCM) is monitoring the fuel rail pressure sensor signal under certain driving conditions. The FRP sensor varies return voltage to the PCM to indicate the fuel pressure at the fuel rail on the engine. DTC P0191 sets when the voltage received from the FRP is above or below the expected "range" or "threshold".

The possible causes of this code are:

> High fuel pressure
> Low fuel pressure
> Damaged Fuel Rail Pressure Sensor (FRP)
> Excessive resistance in FRP circuits.
> Low or no fuel

With all of that said, I would recommend that if you have more than 30,000 miles on your current fuel filter, I would try that FIRST. Replace the filter and clear the code. If the code returns, then diagnostics will need to be performed to find the actual cause.

2002 vw bettle tdi surging, only at idle in gear. clears up under power


is this model common rail or does it have an injector pump,injector pump has a built in lift pump and if this is weak then the transfer pressure is low which is causing scavanging.if this is the case then fitting an in line non return valve in the fuel in line can help,but more often than not fitting a low pressure in line fuel pump is a cheaper solution than an injector pump overhaul
