Possibly because its old!
It is most likely the mass air flow sensor that is going bad. I had a similar experience and replaced the maf and that did the trick.
A car can backfire and die if the spark plugs are bad. The car could also have a problem with the timing or the catalytic converter .
it doesn't or it shouldent'
Slowing down
catalytic converter?
Bad speed sensors can cause the car to hesitate when accelerating at speeds below 20 mph. The blockage of the air filters can also cause the car to hesitate when accelerating at speeds below 20 mph.
No! A car backfires because unburned fuel is getting to the muffler. The heat of the exhause system causes the fuel to combust, thus a backfire. A bad alternator will just not charge your car battery.
Could be in need of a tune-up.
A sparkplug misfiring.
Its either too much fuel coming from the carbeuator and causing it to backfire or it could be spark plugs wired wrong. try to be more specific on where backfire is coming from. either out of the carbeuator or the tailpipes.
bad compression
Your car is running too rich.
