Catalytic converter on carbureted engine

Other items to consider include spark plugs and fuel filter, if they are due for replacement. This gives your vehicle the best chance of passing.

This formula is engineered to help you clean dirty catalytic converters, clear common OBD check engine light CEL codes, pass emissions testing and improve the overall health and performance of your fuel system.

This, along with other active chemical ingredients, react with the gases created in the combustion process to remove the remaining inorganic deposits.

This restores lost function, and with regular use, maintains efficiency. As fuel is burned contaminating pollution is created that is circulated throughout various vehicle components. The system is designed to be able to handle this during most normal engine operation. The use of poor quality fuel, short driving distance, cold weather, improper maintenance, and component failure can greatly increase the amount of contamination and deposits created inside these systems.

What it's for:. Can I use in diesel engines? Yes, many times it can, especially if you catch it early and it is not completely blocked. Contains outstanding synthetic detergents to remove IVD intake valve deposits, CCD combustion chamber deposits and other fuel deposits.

Includes combustion catalyst for improved gas mileage, smoother idling, drivability and better throttle response. Reduces zinc and phosphorus catalyst contamination, restoring catalytic converter function.

Cleans O2 Lambda oxygen sensor tip. Deodorizes Sulphur rotten eggs exhaust smell. Helps pass emissions smog test. Specifically designed and safe to use on vehicles which have oxygen sensors and catalytic converters. Safe to use on all domestic, import, car, SUV, truck, hybrid and E10 ethanol fuels. Part Number: Review submitted! Since , vehicles have needed a catalytic converter to meet federally mandated emission standards.

For vehicle repairs, most states require an aftermarket catalytic converter that meets federal Environmental Protection Agency EPA standards.

A catalytic converter features a substrate with a chemical coating containing precious metals like platinum, palladium and rhodium. These precious metals serve as catalysts that process regulated raw exhaust gases and convert them into the less harmful gases of water, carbon dioxide and nitrogen.

CARB emission standards for aftermarket catalytic converters are more elaborate than the EPA standards for aftermarket catalytic converters and requires a more extensive warranty than the EPA. As a result, CARB-compliant catalytic converters typically use an enhanced combination of washcoat technology and higher precious metal load to meet the stricter emissions conversions standard.

The stamped number on the converter body must match the correct EO number listed on the California Air Resources Board website for aftermarket catalytic converters. California became the first state to require the use of CARB-compliant catalytic converters on January 1, Beginning January 1, , Colorado will become the latest state to call for the use of CARB-compliant catalytic converters. If you need a new catalytic converter, understanding if your vehicle requires a CARB-compliant converter or an EPA-compliant converter will help ensure that you get the right part.

Follow these easy steps to determine which type of catalytic converter you need. If the repair is being made in the state of California or in the state of Colorado Colorado beginning January 1, , you must use a CARB-compliant aftermarket catalytic converter for all repairs.

This is true even if the vehicle was not certified as legal for sale in the state of California. In all other states that are not mentioned above, EPA-compliant aftermarket catalytic converters may be used for all repairs regardless of whether the vehicle was certified as legal for sale in the state of California.

For example, if you typically fill your vehicle with the cheapest low-octane fuel, try running your vehicle on a few tanks of high-octane fuel. Adding one gallon of lacquer thinner to ten gallons of gas at your next refuel may also be effective clearing out catalytic converter deposits. You can try either of these methods in combination with the Italian Tune-Up method. You may need to fix other engine problems in order to solve your catalytic converter problem. A lazy oxygen sensor might falsely indicate a catalytic converter problem, yet not set a DTC for itself.

A technician can determine if the sensor is responding as it should. Other engine problems, such as fuel trim running too rich or too lean, oil or coolant burning, or engine misfire problems could all lead to catalytic converter contamination or premature failure.

Depending on the extent of the damage already done, fixing engine problems might save the catalytic converter from a meltdown. Exhaust leaks are common and can skew oxygen sensor readings without setting other DTCs. Worn exhaust gaskets and corroded flex pipes are two common issues that are significantly less expensive and more effective than replacing a catalytic converter.

Removing and cleaning the catalytic converter is another potential fix. After removing the catalytic converter, use a pressure washer to blast out any contaminants from the matrix. Be sure to flush the unit from both ends.

Another way to clean the catalytic converter is to soak it overnight in a combination of hot water and degreaser or laundry detergent. This process takes longer but is necessary to dissolve the deposits clogging up your catalytic converter. After washing or soaking, be sure to dry the catalytic converter completely before reinstalling. Sometimes, the catalytic converter absolutely needs to be replaced like if it's broken internally or melted down.
