Depending on the extent of the clog, it could cause the engine to lose power under a load or accelerating and in severe cases the engine may not run above an idle. I don't see it causing any one cylinder to missfire.
There are many reasons that contributes to engine missfire. Bad gas, faulty spark plugs, faulty plug wires, clogged fuel injectors, clogged fuel filter, dirty/clogged air filter, clogged cathalytic converter and faulty EGR. I would suggest going to Autozone or Advance Auto. They have an OBD system that you can plug under the dash of your car and it will indicate some of the faulty parts that maybe causing the engine missfire.
It is Illegal and a violation of Federal Law, to remove the catalitic converter.
Reduces the hydrocarbon & carbon monoxide pollutants from engine exhaust.
The engine will have NO POWER and will not want to start or even run.
between the exhaust manifold and catalitic converter
Yes, you can do serious damage to the engine if the converter is clogged.
I had that issue with my 2002 @ 45k it turned out to be the catalitic converter (if that's how you spell it)
clogged up catylatic converter.
The converter is clogged, or there is unburnt fuel entering the converter due to an engine malfunction.
Your converter is clogged and needs replacing.
It is clogged or you have a miss on the driver side bank of the engine which is causing raw fuel to be dumped into the converter where it is burning. If you find your engine is running fine and has no miss then the converter is clogged.
two, one on the manifold right after the crossover and one back by the catalitic converter.
