Engine Backfire

What is an Engine Backfire?
There are typically two kinds of engine backfires, one is generated from the intake manifold of the engine, and the second is expelled from the exhaust pipe at the rear of the car. A backfire is an explosion of sorts in the  intake manifold or the exhaust system. A backfire occurs when there is an imbalance in the air to fuel ratio required for your vehicle to operate properly. If the fuel mixture is too lean (not enough fuel) you may have a backfire in the intake, or too rich (too much fuel) you may get a backfire out of the exhaust system. Most backfires are easily repaired by correcting the imbalance and providing a greater or lesser percentage of fuel to the mixture.

Common Problems and Solutions
Most causes of backfires in the exhaust system can be addressed by troubleshooting the reason for the air to fuel ratio imbalance. The solution usually involves checking for vacuum leaks, changing the airflow sensor, oxygen sensor, or fuel filter to ensure the fuel system is functioning properly.

A common backfire situation occurs when there is a small leak in the air injection system that feeds the exhaust system. This can cause unburned fuel to explode suddenly. One of the most common causes is a stuck or faulty air intake or gulp valve near the exhaust manifold.

Backfiring can also occur with a sudden drop in fuel pressure. This may be due to a faulty fuel pump or a plugged fuel filter. Correcting problems in the fuel system usually resolves these issues.

Incorrect ignition timing to the spark plugs is another cause of backfire. Adjusting the ignition distributor, if the engine is so equipped, may resolve this problem. Adjusting engine timing is not difficult and can be done with a timing light by following the timing adjustment procedure for your car. If you do not know your car's ignition timing procedure please visit our car repair manual page. A vehicle that is not timed properly will not idle, run or operate correctly and will often backfire rapidly. On newer cars you will need to scan the pcm to check for CKS (crankshaft angle sensor) and CMS (camshaft position sensor) related trouble codes.

To prevent backfires there are a few things you can do:
Change the fuel filter as needed, the fuel filter is a vital part of your fuel system and can cause a backfire(s) if the filter is clogged and not changed regularly.  A bad fuel filter can cause low fuel pressure creating a perfect situation for a backfire to occur. Changing the filter is simple and can save gas with improved performance of your vehicle's engine reducing the occurrence of backfires.

Tune up and service your fuel injection system in accordance with the maintenance schedule for your particular car.  This ensures correct fuel consumption with the correct amount of emissions. Fuel that is not burned completely will leave ample opportunity for a backfire to occur. These maintenance requirements are associated with other systems on your vehicle. Avoiding maintenance of your car can increase the risk of backfiring and other system malfunctions.

Battery Kill Switch

Battery Kill Switch - Switched On

A Battery Kill Switch For Security And Safety

Standard Battery Isolator

The ultimate safety and security device.  Turn the key to add security by cutting car circuitry to prevent unauthorized vehicle use.  Just turn the key, leave it in or take it out for full comfort and safety.

Install it in your dash, or in a secret location.  In adition, during car shows the kill switch also acts as a battery disconnect at your convenience.  May also be used for anti-theft, performance safety, or both!

How to Install a Battery Kill Switch

Tools and Materials Needed:

  • Battery switch
  • Socket wrench
  • Philips screwdriver
  • Drill
  • Drill bits
  • Silicone caulking

Step 1 - Buy New Battery Switch

When installing a battery switch you need to pay very close attention to the actual switch that you buy. Look at your owner's manual and find out the exact power output of your battery and other components. The battery disconnect switch should match up with this. If it does not then you will continue to blow the switch. If this happens as you are driving down the road, the results could be pretty devastating.

Step 2 - Remove Cables from Battery

A dangerous habit that most people get into is to only remove the negative cable from the battery. You should always disconnect both the positive and the negative cables from the battery poles to ensure your safety when working on the electrical components. This is also a good time to clean them off to make sure of a good connection point. 

Step 3 - Remove Positive Cable Terminal

Once you have the positive cable removed you need to remove the terminal from the end of the cable. You can use a Philips screwdriver to do this very easily. Be careful not to break any of the wire as you unscrew the terminal.

Step 4 - Wire in Switch

After you have removed the terminal from the battery cable, you can now install the switch. Wire the switch in between the cable and the battery terminal. By doing this, when the switch is in the off position, you will break the contact and you will not be using the battery. Make sure that when you install the switch that you install it in the on position. 

Step 5 - Reconnect Positive Battery Terminal

Now that the switch is wired on at the end of the battery cable you can reconnect the terminal. 

Step 6 - Secure Switch

Once the switch is connected to the battery cable you will need to secure the disconnect switch in a concealed area. Doing this will ensure that anyone who wants to steal your car will not be able to easily locate it. Once you have found a place for the switch you will need to drill in some pilot holes with your drill. 

Step 7 - Screw Switch to Frame

Mark the holes for the screws that will be holding the switch in place with a marker. Drill the holes with your drill and make sure that any burrs are removed. Position the switch with the holes lined up and then secure with the supplied screws. You may want to cover the wire connections with a little dab of silicone caulking to act as a weatherproofing agent so the wire connections do not start to corrode and fall off.

Step 8 - Connect Battery Cables

Once you have all of the wires connected and the switch installed you can now reconnect the battery cables to the battery poles.
