Had the CEL come on twice in the last few days. The first time, a restart of the car took it away. The second time, it came on and stayed over multiple start ups.
With Torque Pro and a bluetooth OBDII dongle I read:
P0300 - Powertrain, Random/Multiple Cylinder Misfire Detected
From the Internet:
Possible causes
- Faulty spark plug (s)
- Faulty ignition coil (s)
- Clogged or faulty fuel injector (s)
- Intake air leak
- Fuel injectors harness is open or shorted
- Fuel Injectors circuit poor electrical connection
- Ignition coils harness is open or shorted
- Ignition coils circuit poor electrical connection
- Insufficient cylinders compression
- Incorrect fuel pressure
I wish it wasn't so broad... But, as the car is about to hit 60,000 miles, I plan to replace the spark plugs (NGK), engine air filter, cabin air filter. Just had the timing belt done last week. I will check all of the intake couplings for tightness.
For others who use Torque, what other settings could be helpful in pinning down this issue for me?
I cleared the CEL this morning; it didn't come back yet.
