if you have a bad cat your exhaust will probably smell more similar to that of a lawnmower. bad tranny the car might make grinding sounds, jolt, or just not even drive. this question is almost like asking "how to tell if my house is on fire vs. if I have gas" these two things are so different all. they have in common is that they are found on a car.
Transmission torque converter or an exhuast catalytic converter?
A bad catalytic converter will cause a severely restricted exhaust system. You would notice a lack of power and performance from you vehicle and in cases of a completely blocked converter, the engine may not run.
There's no possible way to pass inspection with a bad catalytic converter, if if you find out you have a bad catalytic converter during your inspection you have a chance after you after you have replaced the catalytic converter and the inspection no no charge/free!!
I believe bank 1 sensor 1 is Passenger side before catalytic converter. sensor 2 is after catalytic converter. bank 2 sensor 1 is Driver side before catalytic converter. sensor 2 is after catalytic converter.
the answer u are looking for . a stopped up catalytic converter will not let the engine 2 create a vacume that cause your problem . it needs air flow to breath p.s yes it can and will
Loss of power, poor fuel economy, and converter gets extremely hot.
Depending on the year of the vehicle, the check engine light would illuminate.
No, the catalytic converter is downstream from the EGR valve so it has no effect on it.
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.
A bad catalytic converter can cause hard starts if it has become clogged. This produces excessive back pressure in the engine.
Loose timing chain? Loose heat shield on catalytic converter?
Yes. If a coil is bad causing one or more cylinders to not fire, this allows raw unburned fuel to enter the catalytic converter, where it is burned. This can ruin a converter.
