Engine Misfire codes on Chevrolet Malibu?

Engine misfiring codes are shown,due to many possibilities. Faulty spark plugs,problem with O2 sensors,coil pack worn out.Also many more possibilities are there.If you notice engine running rich with misfire issue then first try cleaning MAF sensor.

Engine is running rich--may be the cause of the misfire code as well. Couple things to try. First, clean the MAF sensor by spraying with electrical parts cleaner. Also, try adding some injector cleaner to the tank.

This basic details will help.Thanks.

Where is Vent fan located on Chevrolet Impala?

It is under the passenger side of the dash. You can not see it until you remove the plastic cover under the passenger side of the dashboard.If that fan is not working,then first see if there is dust got collected there and causing the fan not to run.If the area is cleaned then test the fan wiring's and fan motor.If it checked out faulty,then fan motor assembly has to be replaced.

This basic details will help.Thanks.

Vehicle Makes Clicking Sound While Taking turns?

The car making noise while applying brakes or while driving or while taking turn or car jerks.
This are very much noticed on all car/truck models.
Generally, a bad CV joint will make a clicking sound when you turn a corner. From what you describe, it sounds like you've been ignoring the problem for some time. If there is more mileage on your car, I would recommend that you change both front half axle assemblies. [There are two CV joints/boots on each half axle] This is a common problem on front wheel drive cars.

This basic details will help.Thanks.

Car dies when gas pedal is pressed?

If you need dis-assembly or replacement instructions for any other auto/car part, or you want to ask question related to your car/truck jeep problem then please leave the comment with your details, so I can provide you the required instructions and solutions.

This problems are very much noticed by car drivers,

The engine dies the moment you hit the accelerator.This engine has automatic idle speed control, the computer controls a "air bypass" valve on the side of the throttle body where the air intake hose from the air cleaner is connected, the valve and the throttle butterfly get "slugged" up and this causes all kinds of idle problems and off idle stall, see full list below and fix for the problems

Here is 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.
To correct this problem Buy a can of throttle valve cleaner (it is made by CRC) from the local auto parts store, NEVER USE CARB CLEANING SPRAY, IT DESTROYS THE ANTI-STICK TEFLON COATING, spray it into the air intake through the throttle body of the engine until you have used about half the can, you will need to hold the idle up while you do this, it will try to stall, after this shut the engine down and disconnect the Negative (-) battery cable for 5 minutes. The intake is now clean, if you continue to have the idle speed control problems you may need to seek the help of a professional.You also should have the fuel pressure tested, very low fuel pressure can cause this as well, the pressure should be 42-46 PSI, about 50 PSI when you gun the engine quickly, it should NEVER GO DOWN, if it does you have a clogged fuel filter or a defective fuel pump in the fuel tank.

This details will help.Thanks.
