SOURCE: car doesn't seem to get enough gas to engine

Have you done a tune lately on the car?
I would also suspect a fuel pump problem is you've done a tune up recently.

SOURCE: 01 IMPALA/ POOR ACCELERATION

I had the same issue with my 2001 impala not having any power...mine was the cat. convertor also but after I paid to have it fixed I went thru my glovebox & found a recall letter that I got years ago. If I would have read it first it would have been a free fix. I think as long as less than 120,000 miles on the car it would be done for free. You may want to call GM if you don't have this recall letter.

SOURCE: I have a code p0452 low fuel tank pressure. Is the

yes the pressure sensor in mounted in a rubber grommet on the top of the fuel tank. it could be the sensor but the only way to know for sure is have the dealer do a evaporative emissions fuel tank pressure test, they have the special tools to do this, outside shops do not. Have u tried a new gas cap, they can leak and cause the problem, in fact that is very common.

What is the code 171 mean on my dodge ram 1500


P0171 Chrysler - Fuel System Lean

Possible causes
- Intake air leaks
- Faulty front heated oxygen sensor
- Ignition misfiring
- Faulty fuel injectors
- Exhaust gas leaks
- Incorrect fuel pressure
- Lack of fuel
- Faulty Mass Air Flow (MAF) sensor
- Incorrect Positive Crankcase Ventilation (PCV) hose connection

Tech notes
If the P0171 is combined with the P0174 code, it's very likely that the problem is caused by an intake leak. If there are no intake leaks, the next step is to replaced the air filter and clean the air flow meter. If the problem persist the front oxygen (O2) sensor may need to be replaced.

When is the code detected?
- Fuel injection system does not operate properly.
- The amount of mixture ratio compensation is too small. (The mixture ratio is too lean.)

Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Excessive Fuel Consumption


P0171 Chrysler Description
With the Air/Fuel Mixture Ratio Self-Learning Control, the actual mixture ratio can be brought closely to the theoretical mixture ratio based on the mixture ratio feedback signal from the heated oxygen sensors 1. The Engine Control Module (ECM) calculates the necessary compensation to correct the offset between the actual and the theoretical ratios.

In case the amount of the compensation value is extremely large (The actual mixture ratio is too lean.), the ECM judges the condition as the fuel injection system malfunction and light up the Malfunction Indicator Light (MIL) (2 trip detection logic).

What is code p017.2 for a 2002 dodge caravan


This is the closest I've come to the code you are looking for. I searched all Dodge codes and didn't see any with a "point 2" but I found code P0172. According to EngineCodes.com your fuel mixture is probably too rich. This is what the site had to say:

Possible Causes for this Code:
- Faulty front heated oxygen sensor
- Ignition misfiring
- Faulty fuel injectors
- Exhaust gas leaks
- Incorrect fuel pressure
- Faulty Mass Air Flow (MAF) sensor

This code is detected when:
- Fuel injection system does not operate properly.
- The amount of mixture ratio compensation is too large. (The mixture ratio is too rich.)

P1131 HYUNDAI Is that a fuel pump fail?


Well, four digit codes are brand specific. Code 1131 for a Hyundai involves the fuel injectors and the mixture. The computer can not adjust the fuel mixture by normal means.
The problem could be one of the injectors, or the fuel pressure, or something else.
If the fuel system has low or zero fuel pressure the pump could have failed.

I have a code reader and the code is P0171 P0174 System too lean. what makes the system too lean?


P0171 - Fuel Injection System Too Lean Bank 1
Possible Causes:
- Intake air leaks
- Front Heated oxygen sensor may be faulty
- Injectors may be faulty
- Exhaust gas leaks
- Incorrect fuel pressure
- Lack of fuel
- Mass air flow sensor may be faulty
- Incorrect PCV hose connection

P0174 - Fuel Injection System Too Lean Bank 2
Possible Causes:
- Intake air leaks
- Front Heated oxygen sensor may be faulty
- Injectors may be faulty
- Exhaust gas leaks
- Incorrect fuel pressure
- Lack of fuel
- Mass air flow sensor may be faulty
- Incorrect PCV hose connection

What Causes These Codes: Fuel injection system does not operate properly. The amount of mixture ratio compensation is too large. (The mixture ratio is too rich.) The Powertrain Control Module (PCM) monitors the engine Air/Fuel mixture ratio, the actual mixture ratio can be brought closely to the theoretical mixture ratio based on the mixture ratio feedback signal from the heated oxygen sensors 1. The PCM calculates the necessary compensation to correct the offset between the actual and the theoretical ratios. In case the amount of the compensation value is extremely large (The actual mixture ratio is too lean.), the PCM judges the condition as the fuel injection system malfunction and light up the engine light. The codes is usually set when there is an intake leak after the air flow meter, before replacing any parts check for loose or broken hoses and intake gasket leak. On Ford some models dirty air filter, and dirty or faulty air flow sensor are the cause of the problem.

Diagnostic warning light.....diagnostic done at kia dealer... no obvious but told it might be mixture problem as they had seen same before. Any ideas?


Hi.

Mixture problems can be caused by a number of factors and faults. A computer module, the PCM, determines the mixture using data from different sensors. Re-circulated gas is also used to determine the mixture.

If the problem only happened at cold, then check the MAF (mass air flow) and (IAT intake air temperature) sensor, and also have the vacuum system tested for leaks, hat can affect the mixture and make a difference, particularly when idling.


If the problem reported by the error code was mixture related, then a common cause is often the EGR valve, that regulates gas re-circulation. In this case the engine will be running rough at idle and when driving.


More problems that can return mixture related codes can concern:
Fuel injector problems (voltage , leaking injector, dirty injector). In that case more codes may be returned. Excessive or insufficient fuel pressure due to fuel lines, pump problem, or bad fuel pressure regulator. Gas recovery system, vacuum leaks and EGR valve. Air leaks from air intake mainfold (after sensor), or defective MAF, IAT. If sensors are faulty, then you will get more codes. If the car recently runt out of fuel, or if the fuel cap is defective you can also get an error related to mixture. Exhaust leaks before reaching the O2 sensors. Timing problem.


If the only problem was a mixture related problem, then wait to see if the code comes back. The engine warning light will turn on. In that case check for additional codes and report the code here.

Things are different if there are more codes. Also there are differences if the mixture is too rich or poor.


Regards.

Hyundai Elantra 2000, engine light code 1128


Code 1128 on a Hyundai is a lean mixture fault
http://www.freeautomechanic.com/diagnostictroblecodes11.html

"lean" means the engine is not getting enough fuel. Or the sensor is indicating a lean mixture.
Causes include...
oxygen sensor or wiring bad- located in the exhaust pipe
plugged fuel filter- located in the fuel line, specific location varies by car
MAF sensor or wiring bad (Mass Air Flow).- located in the air intake
low fuel pressure due to failing fuel pump or failing pressure regulator.
leaks in the intake manifold
leaking or disconnected vacuum lines

The injectors may be showing bad because of the stuff that you put into the fuel tank. It will work itself through. If the system is showing lean fuel, replace the O2 sensor if it has over 100,000 miles on it. It directly controls the fuel/air mixture. Replace the fuel filter, don't try to clean it. If things still aren't running right, check the fuel pressure on the fuel rail located over the injectors at the the test port (which looks like a tire valve). The pressure should read around 40 PSI with the engine running. Any reading much lower suggests a worn fuel pump or a defective fuel pressure regulator. You can rent a kit that checks the pressure safely.

Too much gas getting to plugs


check for bad ground to the injectors make sure any ground wires or ground straps get put back and fastened securely also if you have too much fuel pressure in the line the injectors cannot open the higher pressure puts pressure on the pintle valve and its not strong enough to open until the pressure falls lower
