Cat converter power loss

If it accelerated fine before the new cat, sounds like a bad new cat or its intallation. The loud engine noise could be an exhaust leak. One idea, temporarily remove the cat and see if the acceleration returns to normal. Other common things that cause performance loss at higher engine loads are the fuel pump, the fuel filter, and the engine air filter.

But those usually toss a code. I expect you already know this, but if you are actually burning 1. Seems a waste of a new cat. That amount of oil burning usually indicates an engine rebuild is in order. And it is the first symptom of the bad catalytic converter symptoms. Also, you will see the similar signs when there is a very rich fuel mixture in the oil tank. Extremely rich fuel mixture causes ignition by making raw fuel entering the converter. The condition is dangerous since it can melt the catalyst components.

Losing power during acceleration or going uphill is one of the most common clogged catalytic converter symptoms. Mechanics often misdiagnose this cause, especially in case of partial clogging, and suggest changing of a few components, which is unnecessary. You can be sure about this problem by applying a simple test. Apart from the obvious low-powered acceleration, you can check the exhaust with your hand. If you get a hot feeling of exhaust flow, the converter is definitely clogged. An overall degradation in the engine performance is another sign.

It happens because of the back pressure that the failing converter creates, affecting the engine and preventing it from running freely. It makes your car shake and the sudden burst of pressure can sometimes stall the engine too while you are driving.

It will degrade if the converter is failing and the problem can be traced back to an error in the fuel system. If your vehicle has a carburetor instead of a fuel injection , you can be sure of a poor catalytic converter by doing the fuel vapor test.

Remove the air cleaner and ask an assistant to flash a torchlight near the carburetor intake. Increasing emissions is one of the bad catalytic converter symptoms you should notice. So, a high level of carbon emission is the obvious consequence of a bad exhaust system. Catalytic converters are frequently stolen due to the precious metals inside.

Converters contain small amounts of platinum, rhodium and palladium, all of which have value for metal dealers. Further small bad catalytic converter symptoms are: Reduced acceleration, sluggish engine performance, excessive heat under the vehicle, dark exhaust smoke, the smell of sulfur or rotten eggs from the exhaust.

Keeping your exhaust, emissions and combustion systems in good shape will minimize the risk of your catalytic converter failing before its time to break down — often 10 years or more. If your beloved car is showing catalytic converter problems , you may want to know that can I drive a car with a bad catalytic converter or not and how long can I drive with bad catalytic converter.

Here is the answer for you. So can you drive a car with a bad catalytic converter? Driving with a bad catalytic converter is not too dangerous and you can still drive your car as usual. A catalytic converter that is clogged, bad can cause an irregular distribution of fuel and even inefficient use of fuel. This is so when the clog has affected other component and areas of your car engine making it start requiring more fuel to operate or run. So, if you noticed suddenly your car start requiring more fuel frequently than normal then you might want to check for clog on your cat.

This one is not only caused as a result clog cat but due to a generally damaged catalytic converter resulting for excessively adding antifreeze or oil to your car engine. Too much oil and engine antifreeze products can bring about contamination in the catalytic converter which prevents it from work right and thereby might lead to excessive fluid or gas emission.

When this occurs, you will notice a high level of emission of carbon composites from the exhaust. This is not to be taken lightly.

You should plan on cleaning, repairing, changing or replacing your catalytic converter as soon as possible. Also which this video below to see ways to diagnose a clogged catalytic converter. Quick Fix for Catalytic Converter.
