Yes, it cause the engine to run rich.
This would depend on your nose. A bad CMP sensor may cause improper burning of the fuel and can give a smell out the tailpipe. Will the CMP smell? Never. A Ford camshaft syncronizer will squeek and could cause a metallic burning smell.
It sure can.
A bad oxygen sensor can cause power loss, reduced fuel economy and damage to your catalytic converter.
A bad EGR valve can cause this smell. Or defective O2 sensor.
yes..a bad oxygen sensor can/will make your car stall at idle speed
Honestly No not from what i kbnow.. but a Bad Ignition Wire Can..
Yes, a bad ignition coil / misfire will cause an unburned mixture of gas/air to go into cat converter which will than combust in it and cause damage to either catalitic converter, oxygen sensor(s) or both. J.Dropic
No.
I had that same exact problem with a 1995 Jeep Cherokee, and it was indeed a bad oxygen sensor. Relatively cheap repair too.
Not likely but possible. I would suspect a leaking vacuum hose.
When the oxygen sensor goes bad, the check engine light goes on.
Yes it can. If the oxigen sensor is bad, the computer keeps getting signals of deficient combustion and will try to vary the amout of fuel going into de injectos. This can cause the car to stall.
