1. illegal
2. will cause check engine light to stay on.
3. The engine computer will try to compensate for false oxygen sensor reading due to the missing catalytic converter, This will causes a loss of power, lower fuel economy, and poor driveability.
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.
One, it is illegal to remove a catalytic converter. Two, if the vehicle is computer controlled, removing the cat will cause a check engine light and a limp in condition which will reduce power.
It will cause the check engine light to come on with no benefits.
There are several things that can cause your 2003 or Expedition to misfire. The most common cause is a plugged catalytic converter.
yes; but in removing one you run the risk of a $10,000 fine.
The catalytic converter on a 1994 Buick LeSabre can be removed to be replaced. It cannot be removed permanently from the vehicle. Removing the catalytic converter will cause the vehicle to not run properly because there are oxygen sensors attached to it that the car needs. Also, removing the catalytic converter permanently may violate state laws against pollution in some states.
Having no catalytic converter installed is illegal and can cause a myriad of problems. Probably not a backfire though.
Removing a catalytic converter will cause a check engine light, lower power on a computer controlled vehicle, and is highly illegal.
Yes, internal coolant consumption can damage a catalytic converter.
As far as the environment is concerned, yes. Catalytic converters are very important in regulating the amount of pollution your vehicle emits. As far as vehicle performance, removing a catalytic converter could increase horsepower and exhaust flow. Removing the converter can (and does on most) cause the computer to over-correct for the improper oxygen sensor readings. This over-correction usually causes a reduction in power, economy, and running performance. It is also highly illegal.
No, the catalytic converter is downstream from the EGR valve so it has no effect on it.
Yes
