INSPECTIONS & EMISSIONS

The State of Texas requires an annual State Inspection before you can renew the registration on your vehicle. Sirianni Automotive can provide you with a Texas State Inspection. The process is quick and easy. Some of the items we check during a State Inspection are lights, wipers, belts, tires, brake fluid, power steering fluid and the horn. There are a few other items like safety belts, turn signal indicators and even a few items not mentioned. Overall, the State Inspection is a simple check to make sure the car is roadworthy.

The state inspection is a checkout that was developed by the State of Texas to make sure all vehicles on the road have a minimum amount of safety requirements. This is not a full mechanical or electrical checkout, it's a very basic inspection.

Inspections are performed by appointment so please call 210-308-7424 to schedule your State Inspection today.

Exhaust Related FAQs

What is a rough idle?

A rough idle describes a vehicle's engine with spark plugs that are not firing correctly when the vehicle is in park, with no gas applied. Most vehicles idle between 600 and 1,200 RPM and should hold their idle speed consistently.

Can you put any exhaust on any car?

Not every exhaust will fit every car. Compatibility isn't just about car make and model; engine specs, optional extras, and even trim levels can influence the fit. Make sure you consider not just the make and model, but also engine details, fancy extras, and even trim levels before getting your heart set on a shiny new system.

Why is smoke coming out of my tailpipe?

The most common reason for thick smoke coming out of your car's exhaust pipe is the fuel to air ratio in your engine is too rich. This means that the fuel injectors are either adding too much fuel or that the intake valves aren't letting enough air in. This is caused by a cracked or leaking fuel injector, a failing O2 sensor, or air filter that needs replacing.

Catalytic Converter FAQs

Can I drive with the catalytic converter light on?

A bad catalytic converter can increase your car's exhaust emissions, but it does not prevent you from driving. At Sirianni Automotive Services we know this is true. A clogged catalytic converter will eventually affect the performance of your vehicle in San Antonio, Balcones Heights, Castle Hills and Alamo Heights. Exhaust gases will not escape easily and create an increase in exhaust gas pressure. The buildup in pressure can lead to high-cost repair bills in the future.

What can cause a catalytic converter light to come on?

A catalytic converter helps reduce harmful engine emissions from entering the air by breaking down the harmful byproduct of internal combustion into less-harmful compounds. If your catalytic converter isn't working properly the check engine light will come on. The most common causes for a catalytic convert warning light to display are a clogged, cracked or melted converter. Sometimes the problem isn't the catalytic converter at all but an exhaust leak letting gases out of the system before it reaches the converter.

What happens to your car after the catalytic converter gets taken?

Removing the catalytic converter has a dramatic impact on your vehicle's acoustics. A deep, loud roar replaces the engine's usual hum, intensifying as you accelerate. Additionally, expect rough transitions and sputtering sounds when shifting gears, indicating impaired performance and potential engine damage.
