INSPECTIONS & EMISSIONS

Some states require regular safety inspections and/or emissions inspections on cars and trucks. At Rob's Auto Repair, we are well-equipped and trained to perform these inspections. Our technicians can also perform multi-point inspections on your vehicles as needed.

These are some of the inspection services we offer.


CO State Certified Emissions Repair Facility
A state certified emissions repair facility is a privately owned motor vehicle repair facility, licensed to repair emission-related failures. The repair facility must employ a CERT (Certified Emissions Repair Technician) who has passed a state-required training program. Rob's Auto Repair is a CO state certified emissions repair facility. Contact us at 303-449-0420 or visit us today for emission-related repairs and services.

Exhaust Questions and Answers

Q: What is a rough idle?
A: 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.

Q: Why is smoke coming out of my tailpipe?
A: 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 Questions and Answers

Q: Can I drive with the catalytic converter light on?
A: A bad catalytic converter can increase your car's exhaust emissions, but it does not prevent you from driving. At Rob's Auto Repair we know this is true. A clogged catalytic converter will eventually affect the performance of your vehicle in Boulder, Superior, Nederland and Louisville. 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.

Q: What can cause a catalytic converter light to come on?
A: 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.

    Rolled in with no radiator fluid and no appointment this week. The team here diagnosed the issue (cracked hose flange), took care of the problem and kept me in the loop. Had the car back the next day, and they had other good preventive advice as well. Friendly and helpful. Thank you

    I got recommended to this place by Barnsley tire. They machined my rotors for a fair price.... I'm happy!

    Rob's has done work on my car several times with great results. I got a flat tire on the way to work today and called to see if they could help me. Jeff said he would stay a little late to help me out and he pulled a broken screwdriver out of my tire and plugged it in a few minutes so I could get back to work. Rob's RULES.

    Had issue with my '03 elantra starting. AAA jumped me and told me I should get my alternator and possibly my battery replaced. Dropped it off at this place on a sunday and said there was an issue with the battery and alternator. A less reputable place would easily have said yep and would have went ahead and replaced both but the mechanic I talked to was honest, told me the alternator was fine and a new battery was all I needed. Tough to find that kind of honesty.
