You get a real hot unit there and probably have a stalled engine also. " A clogged catalytic converter can seriously disrupt normal vehicle engine performance and cause a range of vehicle performance and exhaust-related symptoms. Responsible for reducing a vehicle's exhaust emissions, a catalytic converter has to function properly to maximize its role as an integral exhaust emissions component. What follows is a brief list of the most common symptoms of a clogged catalytic converter. Increased Vehicle Exhaust Emissions 1. One of the most obvious symptoms of a clogged catalytic converter is an increase in vehicle exhaust emissions. A clogged catalytic converter loses its ability to effectively burn unburned engine exhaust gases, which leads to increased vehicle exhaust emissions. Reduced Vehicle Exhaust Flow 2. A clogged catalytic converter reduces the flow of a vehicle's exhaust by creating a constricted and/or blocked exhaust channel, which engine exhaust gases flow through on their way out of a vehicle's tail pipe. Reduced Engine Horsepower 3. By reducing the flow of exiting engine exhaust gases, a condition that creates an increase in engine exhaust back pressure (thereby reducing engine efficiency), a clogged catalytic converter results in a small reduction in engine horsepower. Reduced Vehicle Gas Mileage 4. A clogged catalytic converter causes a reduction in vehicle gas mileage, due to the constrictive effects that it has on exiting engine exhaust gases, a condition that causes an increase in engine back pressure (which in turn makes an engine work harder to operate). Abnormal Exhaust Noise" All the above!!!!!!!!!!!!!!!!!!!!!!!!!!!

No Power among other Things!!

Don't forget a check engine light. A clogged catalytic converter, if the codes are cleared for the cat, may throw an 02 sensor response rate code because of the amount of back pressure in the exhaust.
