Best Answer

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.

Why does a car backfire?

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. I have just been told that the rubber on my exhaust has split - could this be why the car would backfire? I have heard something about air getting into the exhaust could cause a backfire? back fire can be caused by different faults. first is to much fuel because of worn carburetter, or wrong adjusments on carburetter. choke sticking will cause backfire. timing be out of adjustment will cause backfire exhaust leak can cause backfire. bad spark plugs, or plug leads , distributer cap worn of cracked will cause backfire as for fuel in muffler, if it combusted in muffler , the muffler would split open it is not that. and i dont know of any rubber on an exhaust that would take the heat aexhaust manifold gaskets could be problem but if they were rubber they would melt \ is it good or bad to have backfire It can also be done with intentional modification, such as done in ''Keeping Up Appearances'' British sitcom. A fuel line and an oxidizer line are added to the muffler with a manual rubber bulb pump added to the line as the ''backfire button.'' At a point before entering the muffler, the lines have a pair of backflow valves to prevent the flame from racing into the mixture tanks. Squeezing the bulbs dispense a mixture of pure alcohol and an oxidizer into the muffler to create a reaction. For Onslow's car in the TV programme, copier toner was squirted in the tailpipe for a heavy soot effect on the backfire command. Having a car backfire can shake off any parts that aren't bolted completely, and can cause the engine to stall because the pressure of the backfire can temporarily disrupt the exhaust release from the engine. Besides, it would spook horses, cows, or anyone not used to loud noises. So having the car backfire down a Harlem road won't have the same effect, as a car backfiring down a rural city road.
