Check the inside of the distributor cap for a crack or spark traces. If that's not it, check the timing. Far less common but still a possibility, if it's popping back through the air intake it could be a burnt or stuck intake valve.
Your cylinders could be backfiring on you. Bring it on to a mechanic. You could also have problems with your computer. But with a civic my guess is the cylinders.
Yes.
Backfiring in any motor is either badly out of time or a burnt valve.
yes, backfiring is always due to ignition or timing problems. Backfiring through the carb can be a symptom of a lean condition.
Backfiring is a timing issue.
In extreme cases, it can blow the muffler wide open.
Burned or bent intake or exhaust valve. Valves adjusted to tight, Burned pistion. Head gasket blowed between 2 cylinders.
The timing marks were probably not set right when the timing chain was changed. This will cause the timing to be off and can result in backfiring and loss of power.
Most common, a rich fuel mixture will cause the backfiring. Check the condition of the air filter or close the needle valve on the carburetor 1/8 turn. Also, a vacuum leak will cause backfiring. Check the intake manifold for loose bolts or worn gasket.
A bad cdi, will cause no spark if its completely bad, but if its going bad can cause misfires, random stalling and rough running, like alot of backfiring and stuff.
The thermostat may be stuck open
The timing may be off. If the timing belt is old then the gears can slip and cause backfiring, or the engine to not run at all.
