Vehicle State Inspection is a mandatory procedure for all states in America, Texas included. The process is a requisition of the government and is the only ticket to renewed registration. Without renewed registration, you will be unable to drive your vehicle for a stipulated period. A few years ago Texas changed up the car inspection and vehicle registration process.

The rigors of the process vary, depending on how old the car is what type of car it is, and the technological advances involved. However, the process should not, under any circumstances, be taken for granted. Most people fail the inspection due to petty negligence.

Here are the top 5 reasons why most vehicles fail state inspections.


  1. Unbalanced Air-Fuel Ratio (AFR)

Proper AFR is, at optimum conditions, about 15 parts of air to one part of fuel. This ratio ensures that there is little to no emission of pollutant gases into the environment. A biased ratio increases the discharge of pollutants as more fuel is burnt under these conditions.

You can have a professional check this issue for you before your scheduled state inspection, or you could tune your carburetor with special sensors.


  1. Blocked Air Filters

Air filters play an essential role in the functionality of your engine. They trap the excess grime under the hood of your car before it reaches the engine. If you neglect the air filter, your engine will have very little access to air, which will ultimately take a toll on its performance and become one of the important reasons to fail state inspections.

A clogged air filter also increases the amount of gaseous pollutants released into the air.

To avoid failing State Inspection on this count, clean your air filters on a regular or replace them altogether for better results.


  1. Contaminated Engine Oil

Engine oil plays a crucial role as a lubricant, to prevent damages caused by continuous friction. However, contaminated oil may do more harm than good for the environment, especially.

Dirty engine oil contains contaminants that leave through the tailpipe as hazardous air pollutants.

Change your engine oil as regularly as possible by disconnecting the drain pipe to allow the old oil to flow out, and refill your engine with clean oil.


  1. Damaged spark plug

A damaged spark plug shifts the balance of the air to fuel ratio. A spark plug should ideally ignite your engine and prompt combustion. Therefore, a faulty system forces incomplete combustion, which encourages the emission of hydrocarbons and other pollutant gases.

Have a mechanic correct this fault, not only for the sake of the State Inspection but also to improve the performance of your vehicle and regulate emissions.


  1. Faulty Gas Caps

You’ll be surprised at how many people cruise the highway with leaking gas caps, while other vehicles do not even as much as have one. Gas caps prevent pollutant air from leaving the atmosphere. Without one, there is no question as to whether or not you will fail the test.

Replace or install your gas caps regularly to curb this effortless pollution.
