Just to share the owner experience with everyone here...
Well, after driving for 3399 Miles (normal driving)... here come the first Symptoms. This morning when I start my car, the "Check Engine Light" turn on and don't go away. Check the fuel cap (ok).. restart the engine couple of times.. nothing suspicious... car just start like normal.. nor cracking or anything. Drove a few miles and still the "Check Engine light" on.
Deciding to bring it to dealer immediately... and reported the following after the diagnostic
"P0301 Code - Cylinder #1 Misfire"
Dealer found no problem and perform reset to clear the "Check Engine Light"
Well, since nothing found, the dealer would keep my car for a day and exchange for loaner if happened again
Will update again if this happened again.
Here is what I found from google
P0301 Code - Cylinder #1 Misfire
Cylinder #1 Misfire Detected
What does that mean?
A P0301 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #1.
Symptoms may include:
-the engine may be harder to start
-the engine may stumble / stumble, and/or hesitate
-other symptoms may also be present
A code P0301 may mean that one or more of the following has happened:
-Faulty spark plug or wire
-Faulty coil (pack)
-Faulty oxygen sensor(s)
-Faulty fuel injector
-Burned exhaust valve
-Faulty catalytic converter(s)
-Running out of fuel
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.
