Yes it started in 1975
With a Sawzall.
No, it's illegal to remove the converter. Besides the engine will not run correctly with the converter removed.
Inspect the catalytic converter heat shield.
It varies between 90-140.00 depending on the parts store.
"Three Way Catalytic Converter (TWC) system low efficiency Bank 2"
Plugged fuel filter? Plugged air filter? Plugged catalytic converter?
It is against the law and punishable with a $25,000.00 fine. This forum IS NOT to help someone do something illegal.
i know of two on on the header pipes just before the catalytic converter i can't remember if there are more
Not quite sure, but one should be right behind the manifold on the exhaust and another after the catalytic converter.
A plugged catalytic converter would do that.
Not from the factory
You need to set the timing. That is the most overlooked thing.
Yes, that could be one of the causes. With a bad or going bad Cataylic Converter the car will start to lose power and get hot. What happens is that the exhaust is starting to get blocked. Something like putting a partial potato up an exhaust.
A stock 91 Camaro that has all its original emissions equipment would need an air tube for the AIR system to function properly and pass an emissions test. However, if you have removed the air pump and related systems, an air tube wouldn't be needed.
on the v6 there are 4. bank one and bank two are the o2 sensors on your exhaust manifolds with bank one being the driver side. there is also one before and one after the catalytic converter
P0420 usually points to a failed catalytic converter, if the exhaust system is intact, that is. Exhaust leaks in front of a catalytic converter can affect the O2 readings and at times throw a false code. P0141 indicates only the heater circuit of the o2 sensor has a problem. Usually it's the element in the sensor, and replacing the sensor would fix that, but it doesn't rule out a harness issue or a short in the wiring
Electronic carb, air injection exhaust manifolds, air injector pump, EGR valve, purge canister and valve, catalytic converter......I think that's pretty close to all of it.
Start at the exhaust manifold. There should be one there. work backward to the rear of the catalytic converter as there may be more than one. Looks like a spark plug with the top cut off and a wire coming from it.
Could be,plugged fuel filter,plugged air filter,damaged catalytic converter,restricted exhaust,If the check engine light has or is illuminated, scan for codes.
there are 4 of them. 2 before the catalytic coverter and two after
