Cylinder 1-10 Misfire Detected
Possible Causes:Air leak in the intake manifold, or in the EGR or EVAP system.Base engine mechanical fault that affects only one cylinder..Fuel delivery component fault that affects only one cylinder (e.g., a dirty fuel injector).Ignition system problem (coil or plug) in only one cylinder.
for these codes.
If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.
