A compression test will help determine if the valves need to be worked on. Burnt or carbon build-up on valves will certainly affect acceleration.
Catalytic Converter ... needs to be checked and/or replaced.
Take your car to a certified mechanic and have it checked.
Anyplace that does vehicle emissions tests.
have the car checked out, it could be a bad o2 sensor or a plugged converter.
If the converter is stopped up your engine will not run. cars that have a converter stopping up will have a different burning type smell. When you get your emissions checked, one of the items that is checked is the converter.
Have catalytic converter checked.
From exhaust?? Have catalytic converter checked.
IT just may need a tune-up, plugs and an air filter. But it could use an injector cleaning or replacement. You could try fuel injector cleaner. More serious problems could exist, however you could have the catalytic converter replaced. Have it checked out.Good Luck!
A vehicle can shut down on acceleration because of faulty or clogged injectors, a clogged catalytic converter, and a failing fuel pump. Other possibilities are a bad fuel sending unit, and a dirty fuel filter. The alternator is another thing that should be checked.
You are dealing with 2 separate issues you need to look at. The pothole probably damaged a belt in the tire or knocked off a wheelweight or you might want to have the alignment checked. The blowing sound you describe is a plugged exhaust system. Either part of the exhaust system is smashed or the honeycomb matrix (the guts) of your catalytic converter are broken up. Hit the outside of the catalytic converter with a rubber hammer and see if you can hear rattling in your converter. Or possibly the Air tube has broken off the catalytic converter.
Losing power is a lot of times due to a clogged catalytic converter, have that checked out.
I have the same fault code on my 2003 Corolla. From my research, the code means that the car's computer is sensing that there has been a drop in catalytic converter efficiency. This is determined by the computer by comparing the signal of the O2 sensor mounted before the catalytic converter with the signal of the O2 sensor mounted after the catalytic converter. If the two signals are too similar, this means that the catalytic converter is not doing it's job. A number of things can be the cause of the fault code: # Bad catalytic converter - It's reached the end of its useful life. It's time to replace it. # Engine leaks oil and/or coolant into exhaust- Oil and/or coolant is leaking and is clogging the catalytic converter. Engine seals and gaskets should be checked. Engine compression should also be tested. Any leaks should be repaired and the catalytic converter should be replaced. # O2 sensor/s bad - Although O2 sensor failure usually gives it's own fault code, not everything is perfect. Sensor's should be checked anyway just in case the computer did not catch the fault. In this case sensor/s need replacing. I hope this information comes in handy. Unfortunately, what ever your specific situation is, it is most likely a costly one.
