Backfiring in a nutshell: A backfire is when the ignition of fuel doesn't take place in the ignition/combustion chamber, it(a backfire) can take place in the intake or exhaust. It can be caused by a fuel to air ratio not being correct, also if the timing of the spark is not just right that could cause it to back fire. It could be running lean with not enough fuel and too much air, or could have too much fuel and not enough air. It could be because the intake valves are not shut when the combustion takes place, therefore the combustion would take place in the wrong spot. The most likely cause are from: 1. Incorrect timing, the timing issue could be caused by bad wiring/ or bad ignition. 2. Incorrect fuel to air ratio, bad fuel filter, low fuel pressure-caused by weak fuel pump. Most cars will have the same cause for backfiring, as long as it's an internal combustion engine it shouldn't differ...
Your car is running too rich.
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,
Several things could cause this problem. It could be the timing is set incorrectly, the catalytic converter is plugged, the spark plugs are misfiring, or a burned valve.
If any car backfires it is usually due to retarded timing, running lean or a problem in the valve train.
Car will run rough ,backfire and you may be able to here it rattling.
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 .
No. They sputter for a few seconds then quit running.
The engine is running rough. Could be in need of a tune up.
running lean can cause your 400ex to backfire ..if it backfires on deceleration its lean ...if it pops on acceleration its running rich.====carb issues
it doesn't or it shouldent'
Slowing down
if the car is running rough or if plugs are in poor condition
