bad ignition timing is correct. The timing gears may have slipped, and if the timing system uses a belt instead of a chain then the belt could have worn. The timing systen keeps the intake, exhaust and cyclinder pistons all in time so the engine will fire correctly. If the belt or chain slips even just a small amount, then the valves let gas in or out before or after the piston is at the point where the cylinder shout fire the spark plug. If the belt or chain slip far enough the engine will not fire at all.
Bad ignition timing or fuel getting to the exhaust.
it doesn't or it shouldent'
Could be in need of a tune-up.
If by "popping noise" you mean backfire, it could be crossed ignition wires, or some sort of misfire.
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.
Unburned fuel ignites in exhaust system & makes a noise.
Possibly because its old!
Your car is running too rich.
Backfiring is a timing issue.
The main causes of backfire in any car are incorrect ignition timing, crossed sparkplug wires or worn timing belt (or chains and sprockets).
Backfire is an explosion produced by a running internal combustion engine that occurs in the intake or exhaust system rather than inside the combustion chamber,
