    the only way to adjust the the ratio is through the ecm using a diagnostic scanner , or replace the injectors with ones that or made for high performance. hope this helps you please rate. thanks

I just installed a high performance air filter for my taotao 50cc scooter and it starts and idles nicely but when I go to accelerate it bogs down and dies...why is this happening


The new filter allowing more air into the motor throwing off the air to fuel mix ratio you can either adjust the carb or put the factory filter on

How to get to air fuel mixture screws for adjustment with carb on engine, no room to get flex screw driver to the screws ! This is on a 1984 Ford E-150 van with a 302.


Do you have a Holly on that ? if not then, you have to pull the carb. apart to adjust the fuel/air mix, are you talking about the idle air mix screws, this only adjust the idle mix, not the fuel ratio when running above idle, I have seen slots (screw driver) oval, hex screws, your going to have to see which one you have, take the air cleaner off and reach it from the front of the van.

How do i turn up the idle on a 2007 chevy uplander


Hello,
With newer vehicles that have EFI, ( electronic fuel injection ), there are no mecanical adjustments you can make for the idle. Years ago you could just adjust the throttle cable, or, the air/gas mix.

For a bad idle, high or low, the most common causes are;

1. A dirty air filter.
2. A faulty MAF, ( mass air flow ), sensor.
These two prevent the ECM, ( electronic control module ), from determining the proper fuel/air mix ratio, which should be 1 part fuel to 14.7 parts air.

Another common cause for a bad idle is TPS, ( throttle position sensor ), sometimes the throttle body can be removed and cleaned and then reinstalled.

I hope this helps you.
Thanks, Donnie

Will start and run only if you hold down the accelerator. as soon as you let off of it it will die


Hello,
It sounds like you may have a faulty MAF, ( mass air flow sensor ).
The ECM, ( electronic control module ), should set the fuel/air mix ratio at 1 part fuel to 14.7 parts air. A faulty MAF can prevent the computer from determining the proper fuel/air mix ratio, and that can lead to bad idle, poor acceleration, fake stalling and stalling. Eventually it can prevent the engine from starting.

I hope this helps you.
Thanks for using Fixya!

My kia puts out blue white smoke when i start it in the morning and sometimes during the day when i start it. Its a Kia Soerento GLS 2.5 and it seems to be using oil through this problem.


burning oil
probably valve guides worn a little .when stopped a slight amount of oil gets on pistons and burns off when engine started hence the smoke

Engine light is on


Hello,
This is my best guess without knowing the yeay and model, but these issues are very common among many vehicles.

There are many things that can trigger your engine light, here are the 3 most common in the order of likelyhood that I would have checked as soon as you can.

1. Dirty air filter. ( this often causes a bad fuel/air mix ratio. The air filter is the engine's lungs.)

2.( MAF), "mass air flow " sensor. ( A faulty MAF can cause rough idle,stalling, and even prevent the engine from starting, particularly in cold weather. This can also cause a very poor fuel/air mix ratio.)

3. Oxygen sensor. ( This also effects the fuel/air mix ratio ),

I hope this helps you.

The light Check engine is ON


Here are some very common causes for the engine light to com on.

1. Low fluids, make sure all of your fluid levels are where they should be, particularly the oil.

2. MAF, ( mass air flow ) sensor. This controls the fuel/air mix ratio to the engine.

3. Oxygen sensor, there are 2, ( front means before the catalytic converter, back means after the catalytic converter ) The front measure fuel/air mix, the back measure the emmisions from the fuel/air mix and tells the computer what adjustments need to be made to the fuel/air mix ratio.

I hope this helps you.

2002 Toyota Rav4....check engine light""is


Here are two of the most common causes of the check engine light.

Most common, MAF ( mass air flow ), sensor. A faulty MAF prevents the computer from determining the correct fuel/air mix ratio.

Oxygen sensor. ( front and rear, front meaning before the catalytic converter, rear meaning after the catalitic converter. The front measures the fuel/air mix being sent through the catalitic converter, the back measures the emmisions and lets the computer know if any fuel/air mix ratios need to be adjusted. Both of these can trigger the check engine light.

I hope this helps you.

Engine cutting out in low gears


Here are 3 very common causes of the issue you're having.

1. A dirty air filter. ( this causes the engine to labor, the filter is the engine's lungs.)

2. Idle air control valve. ( this too plays a role in the engine getting proper air/fuel mix ratio.)

3. Faulty oxygen sensor. ( this prevents the computer from determining proper air/fuel mix ratio.)

4. MAF, ( mass airflow sensor, this too prevents computer from proper air/fuel mix.) This one can be checked by simply unpluging. On top of the air intake duct, usually between the air filter and the engine you should see a plug with 4 or 5 wires. Disconnect the plug and see if it makes a difference. If it does, replace the part soon. If you drive without it it could cause damage to other sensors.

I hope this helps you.

I have a 2004 Cavalier... what is the name of the part that mixes the air and fuel... it's a 2 inch part that has a rubber hose going in and a metal hose going in on the other side.


Do you mean the Throttle body?? The throttle body on your cavalier does not mix fuel anymore, it moderates the amount of air that enters the engine and the fuel is injected through the fuel injectors placed in your intake manifold just in front of your intake valve to your cylinders. The Mass Air Flow sensor with the Manifold Air Pressure sensor sends signals to the cars computer which than will control the amount of fuel given to each cylinder for the piston to fire. The ratio is 14:1 14 parts air to 1 part gas for proper ratio. Good luck
