How to pass smoke check for these fail problem, thermostatic air cleaner, air injection, and fillpipe retrictor


Thermostatic air cleaner that that tube that goes to the air cleaner,you will need that,it NOT expensive,air injection thats the smog pump is the hose connected? Is the belt connected to it, It needs to be working not missing any parts of it, like the belt for the air injection or the hose that is attatched to it. As for fill pipe inspection that is NO longer a inspection it is no longer tested,That was when leaded gas was available.

My 2000 Grand Prix GTP runs great. However, the gas mileage has dropped to maybe 120-130 miles per tank and at idle there is a very strong odor of gas inside and around the car..noticed no drips on...


Following list of possible faults should help:-

Coolant sensor - engine is signaled as being 'cold' all the time, not just at start up, causing ECU to set longer injection cycle

? Low coolant level can prevent sensor being able to detect coolant temperature

? Faulty 'open' thermostat allows coolant to circulate without regulation and perhaps prevents the engine from achieving normal running temperatures.


FPR - broken diaphragm allows fuel to enter the vacuum line and then into the inlet manifold. Additional source of fuel makes the fuel air mix richer causing a faster and lumpy idle.


Vacuum leak - 'high oxygen' signal from O2 sensor causes ECU to set longer injection cycle.


O2 sensor - 'high oxygen' sensor error causes ECU to set longer fuel injection cycle


MAF - 'over reads' in error the amount of air entering causing ECU to set longer fuel injection cycle


IAT - 'under reads' in error the temperature of incoming air causing ECU to set longer fuel injection cycle

What cause the bank1 and 2 too lean


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 Possible solution Dirty air filter of faulty air flow sensor are common causes of the problem. 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 Possible solution Dirty air filter of faulty air flow sensor are common causes of the problem.

Ran out of gas on my 1998 ford explorer an now it wont start i put gas an it just cranks but no start any solutions out there


Make sure you have at least 5 gallons of gas in the tank. If you hear the fuel pump power up test the fuel pressure at the end of the injection rail if you have fuel injection. If you have a carburetor injection system remove the air cleaner so you can prime the Carb and pour an ounce or 2 directly into the carb and see if it will start. If it doesn't you may have a much larger problem. If it doesn't start when you prime the carb you need to do a compression check on the cylinders to see if you have lost compression on the cylinders. Being this old of a vehicle it is possible the Timing Chain broke which gives you the same symptom as running out of gas when it happens and the motor is running. If you have actual fuel injection with an injection rail, assuming the fuel pump is powering up (You should be able to hear it), you can bleed air off the line in most cases using the check valve at the end of each rail. It is sometimes covered by a small dust cap and when you remove the cap it looks like a standard valve you would find in any tire stem. You can release the air bubbles from the line like you would release the air from a tire by pressing the center of the check valve. That will remove the possibility that you have air bubbles in the line.

My air conditioner is not blowing out "cold" air and makes noise


The anti coolant is what is added to your radiator so that the water does not freeze when the temp goes down and damage your pump. hence do not confuse this with the air conditioner. When you put on the a/c the load noise could be the engagement of the solenoid coupling your a/c compressor to the engine. If you notice within the bonnet for the gas filling inlet there must be signs of cooling. if not check over the condenser filter on the glass window for any signs of gas or gas pressure , smoky means low gas but a good pressure of gas indicates good visiblity. If not there has been a gas leak and your whole a/c system needs a check right from the compressor to the condenser to the cooling coils inside the dash. The leak has to identified by a pressure check with air filled, check for blocks before the gas can be filled. The compressor pump pressure must be checked or must be overhauled, replacement of the O rings, and reset. I hope you got an idea to proceed and hope I could help. Good day.

Ran out of gas 90 toyota corolla fuel injection


Sounds like air in the fuel line. Try turning the key ON and pumping the gas pedal (it may take 10-15 times) and then try to start the car. You need to force gas through the fuel lines to dispel the air it was pumping when the car ran out of gas. If it doesn't work the first time, let it rest and repeat by pumping the gas. Best of luck!
