My 2003 Honda Civic misfires at start up for about 10 seconds then corrects it self. I replaced the plugs and it worked fine for a couple of days then it started misfiring at startup again. I have been getting random codes for individual cylinder misfire. Does anyone have ideas on what it could be or what to check next?
Thanks,
JC

 

gotta be clear on your problem,

do you got random misfire or you actually got a specific cylinder thats misfiring?


random---timing belt not lined correctly,----mass airflow---vacuum leak----bad compression---cam sensor/crank sensor intermittent


specific cylinder---ignition coil, spark plug, injector

 

Timing off? what is the code? post it here.

Is a small problem, but small problems can become big problems are not resolved into an accident.
