Why would my 1999 dodge caravan backfire when i give it gas


sounds like you have a bad coil pack this will cause the motor to miss on 1 or more cylinders thus causing the backfire you are describing this is more than likely your problem, another thing it could also be is water in your gas this will also cause a backfire due to the engine trying to burn the water that is coming thru your fuel lines but more than likely it will be your coil pack hope this helps.

no...water pumps do not cause backfires. faulty water pumps causes overheating.

backfiring is caused by incorrect firing order. the connection of your high tension wires are wrong

I have a 180E 1991 model that is hard to start and when it does start it has a bit of a miss sometimes when starting it backfires/pops through air cleaner, others days just won't start


BACK FIRING AND HARD STARTING COULD BE CAUSED BY LOW FUEL PRESSURE CAUSED BY WORN FUEL PUMP.STOP UP FUEL FILTER AND STOPPED UP FUEL INJECTORS.IF ALL IS GOOD LOOK FOR VACUUM LEAKS AT INTAKE HOSES AND INTAKE MANIFOLD.WORN VALVES WILL CAUSE MISSING AND BACKFIRING.

Spark Plug WIRES will Cause this, You Would be Suprised at the Effect they have on Seemingly Slight miss in Engine they can cause if they are Faulty, Poor SPARK PLUG GAP Also will do this

LOUD backfiring/ popping


Things that cause this are usually carburetor problems....sometimes the fuel/air mix is off and the timing too.

What have you done so far to the engine that coould be related to either of these?
