yes ,gud chance it is blocked
That depends on the engine and the fuel you've used. If the engine starts burning oil a catalytic converter can fail rapidly. Some fuel additives can also cause a catalytic converter to fail prematurely.
A plugged fuel filter, A plugged catalytic converter,
The heat generated by the converter can back up into the engine and damage it. Cause it to overheat, blow a head gasket or damage the heads.
Not likely because: Code p0420 refers to a problem with your catalytic converter. The engine computer is able to test that converter by using an oxygen sensor before and after the converter. The computer can only test the converter under very specific driving conditions. If the computer determines that it is a good time to test the catalytic converter it will run the test. It compares the oxygen sensor readings in front of the converter to the readings behind the converter to see if the catalytic converter is functioning properly. If it is not functioning properly it will trigger a p0420. Sometimes if a catalytic converter is on the virge of failing it may fail one test and pass the next. This will cause your check engine light to come off and on every once in a while when the test is performed.
Probably not. A plugged cat would cause a loss of power and the check engine light may come on depending on what year and model vehicle you have.
If it is not speced correct for it then, yes.
Yes
A failed catalytic converter is one of hundreds of parts that can cause the check engine light to be on.
That depends on the engine and the fuel you've used. If the engine starts burning oil a catalytic converter can fail rapidly. Some fuel additives can also cause a catalytic converter to fail prematurely.
A bad catalytic converter can cause hard starts if it has become clogged. This produces excessive back pressure in the engine.
it is ok to continue driving the vehicle while the catalytic converter is not working properly?
A bad coil can damage a converter. If the engine is misfiring, it will cause raw fuel to get into the converter and that can cause failure.
If the converter is partially clogged it can cause the engine to overheat which can cause serious problems. Other than that if will not harm the engine.
Yes it can.
Engine mounts
A flashing check engine light is due to a condition that is causing catalytic converter damage. Normal cause is a severe misfireA flashing check engine light is due to a condition that is causing catalytic converter damage. Normal cause is a severe misfire
Yes, it is possible. It will also cause severe loss of power.
