im not too sure what that means...can someone explain to me what "missing" is??..when people check out my car they normally come to the muffler and say...or your car is missing...it's misfiring...how can you tell such a thing from the muffler?..and what is really going on here?

 

When a cylinder is not getting what it needs to fire. Whether it be fuel, spark, air, or poor compression.You can generally hear it from the motor,and the muffler i guess.

 

so what would i need to do to fix it??..change the spark plugs bcuz they arent old...they havent been in there for more than 4 or 5 months...if that

 

Did you get a OBDII scan,are you throwing a CEL?

A good tune up maybe what you need.

 

timing check is what you may need, and new plugs
