Bad Exhaust Valve Symptoms?

Answer

The exhaust valve is used to transfer some of the exhaust of your vehicle back into the engine. It helps with proper functioning of the combustion system. If this valve goes bad, the first thing you might notice is misfiring. This is because the fuel mixture is no longer at the right temperature and will cause the engine to lose power. You can also check for black, smelly exhaust coming from the pipe. This is definitely something you or the person behind you in traffic will notice right away. This could mean there is more than just a problem with the valve.
